Hierarchical Porous Nitrogen‐Doped Spray‐Dried Graphene for High Performance Capacitive Deionization
Publisher: Wiley
Date: 05-02-2022
Abstract: Graphene foam materials have attracted particular attention for capacitive deionization (CDI) applications due to their robust conductive framework and open three‐dimensional porous structures. However, their salt adsorption capacities (SACs) are limited by the bland macropores and poor compatibility with aqueous environments. Herein, hierarchical porous nitrogen‐doped spray‐dried graphene (N‐SDG) is prepared through a spray‐drying method followed by low‐temperature nitrogen doping. The resulting material exhibits hierarchical porosity and a nitrogen‐rich carbon framework which demonstrates an improved SAC of 19.6 mg g −1 in 500 mg L −1 NaCl solution, amongst the highest reported for graphene‐based CDI materials. The method herein demonstrates a commercially attractive approach for the production of N‐doped porous graphene material for CDI applications. These findings are expected to underpin new developments in low‐cost graphene‐based materials for a range of applications.

Their role as supercapacitor electrodes is discussed in detail. This review is specifically focused on the concept of material synthesis, techniques for electrode fabrication and metrics of performance, predominantly covering the last four years.

MOF-derived nanoporous carbons with diverse tunable nanoarchitectures
Publisher: Springer Science and Business Media LLC
Date: 05-09-2022
DOI: 10.1038/S41596-022-00718-2
Abstract: Metal-organic frameworks (MOFs), or porous coordination polymers, are crystalline porous materials formed by coordination bonding between inorganic and organic species on the basis of the self-assembly of the reacting units. The typical characteristics of MOFs, including their large specific surface areas, ultrahigh porosities and excellent thermal and chemical stabilities, as well as their great potential for chemical and structural modifications, make them excellent candidates for versatile applications. Their poor electrical conductivity, however, has meant that they have not been useful for electrochemical applications. Fortuitously, the direct carbonization of MOFs results in a rearrangement of the carbon atoms of the organic units into a network of carbon atoms, which means that the products have useful levels of conductivity. The direct carbonization of zeolitic imidazolate framework (ZIF)-type MOFs, particularly ZIF-8, has successfully widened the scope of possible applications of MOFs to include electrochemical reactions that could be used in, for ex le, energy storage, energy conversion, electrochemical biosensors and capacitive deionization of saline water. Here, we present the first detailed protocols for synthesizing high-quality ZIF-8 and its modified forms of hollow ZIF-8, core-shell ZIF-8@ZIF-67 and ZIF-8@mesostuctured polydopamine. Typically, ZIF-8 synthesis takes 27 h to complete, and subsequent nanoarchitecturing procedures leading to hollow ZIF-8, ZIF-8@ZIF-67 and ZIF-8@mPDA take 6, 14 and 30 h, respectively. The direct-carbonization procedure takes 12 h. The resulting nanoporous carbons are suitable for electrochemical applications, in particular as materials for supercapacitors.

An Overview of Cellulose‐Based Nanogenerators
Publisher: Wiley
Date: 02-2021
Abstract: Developing nanogenerators (NGs) is achieved by exploiting the piezoelectric, triboelectric, and pyroelectric effects of both organic and inorganic materials. Many exhibit beneficial electrical properties (dielectric, conductive, or insulating) or have surfaces that are polarizable upon friction or physical contact. Recently, biomass‐derived materials and recycled materials, whose electrical activity can be induced, are explored for application in the design of more sustainable, cost‐effective, biodegradable, disposable NGs, and have demonstrated a wide range of output (microenergy) power densities. Among them, cellulose, the most abundant biopolymer, is found to offer excellent opportunities for designing and manufacturing NGs with multifunctional capacities. Cellulose can be derived into varied forms with multifunctionalities and physical morphologies. This account provides an overview of how cellulose is utilized in creating NGs based on piezoelectric, triboelectric, and pyroelectric effects. Because the mechanical properties of cellulose are tunable, current research trends on NGs originate with the triboelectric effect. The discussion here focuses on design, fabrication methods, achievable electrical power output, and combinations with other materials and devices. Challenges in efficient fabrication and consistent power densities, and opportunities for integrating different technologies and developing more sustainable (in terms of economic, environmental, and ecological) nature–human–machine interfacial devices are also discussed.

Abstract: Energy storage devices such as electrochemical supercapacitors, with high power and energy densities are required to address the colossal energy requirements against the backdrop of global warming and the looming energy crisis. Nanocarbon, particularly two-dimensional graphene and graphene-based conducting polymer composites are promising electrode materials for such energy storage devices. Owing to their environmental stability, the low cost of polymers with high electroactivity and pseudocapacitance, such composite hybrids are expected to have wide implications in next generation clean and efficient energy systems. In this feature article, an overview of current research and important advances over the past four years on the development of conducting polyaniline (PANI)-graphene based composite electrodes for electrochemical supercapacitors are highlighted. Particular emphasis is made on the design, fabrication and assembly of nanostructured electrode architectures comprising PANI and graphene along with metal oxides/hydroxides and carbon nanotubes. Comments on the challenges and perspectives towards rational design and synthesis of graphene-based conducting polymer composites for energy storage are discussed.
Cathode Choices for Rechargeable Aluminium Batteries: The Past Decade and Future
Publisher: Lab Academic Press
Date: 2023
Abstract: Rechargeable aluminium batteries are a promising alternative battery technology compared to lithium-ion batteries, because of the high theoretical capacity, low cost and high safety of aluminium. The past decade has witnessed the rapid development of rechargeable aluminium battery technology with the focus on exploring high performance cathode materials and investigating their charge storage mechanisms. However, the challenges in the cathode research including inadequate capacity, sluggish reaction kinetics and inferior cycling stability still remain. Various strategies have been attempted to address these challenges to realize the advantages of rechargeable aluminium batteries. The present review aims to collect the comprehensive body of research performed in the literature hitherto to develop interaction/conversion/coordination type cathodes for rechargeable aluminium batteries. Future research directions and prospects in rechargeable aluminium battery field are also proposed.
Novel amino-acid-based polymer/multi-walled carbon nanotube bio-nanocomposites: highly water dispersible carbon nanotubes decorated with gold nanoparticles
Publisher: IOP Publishing
Date: 13-05-2009
DOI: 10.1088/0957-4484/20/22/225608
Abstract: A well-reproducible and completely green route towards highly water dispersible multi-walled carbon nanotubes (MWNT) is achieved by a non-invasive, polymer wrapping technique, where the polymer is adsorbed on the MWNT's surface. Simply mixing an amino-acid-based polymer derivative, namely poly methacryloyl beta-alanine (PMBA) with purified MWNTs in distilled water resulted in the formation of PMBA-MWNT nanocomposite hybrids. Gold nanoparticles (AuNPs) were further anchored on the polymer-wrapped MWNTs, which were previously sonicated in distilled water, via the hydrogen bonding interaction between the carboxylic acid functional groups present in the polymer-modified MWNTs and the citrate-capped AuNPs. The surface morphologies and chemistries of the hybrids decorated with nanoparticles were characterized by transmission electron microscopy (TEM) and UV-visible absorption spectroscopy. Additionally, the composites were also prepared by the in situ free radical polymerization of the monomer, methacryloyl beta-alanine (MBA), with MWNTs. Thus functionalized MWNTs were studied by thermogravimetric analysis (TGA), field emission scanning electron microscopy (FE-SEM) and TEM. Both methods were effective in the nanotube functionalization and ensured good dispersion and high stability in water over three months. Due to the presence of the high densities of carboxylic acid functionalities on the surface of CNTs, various colloidal nanocrystals can be attached to MWNTs.

Architectures of Bilayered Gold Nanoparticles on UV Cross-Linked Poly(4-vinylpyridine) Thin Films
Publisher: American Scientific Publishers
Date: 2009
Abstract: A generic approach for immobilizing gold nanoparticles (GNPs) and the construction of multilayered gold structures are reported. The process involves the use of UV cross-linked poly(4-vinylpyridine) (P4VP) thin films for the immobilization and construction of multilayered GNP architectures. P4VP thin films were prepared by spin-coating of the polymer solution onto silicon wafer substrates which was then cross-linked via UV exposure. GNPs, about 70 nm were immobilized via electrostatic adsorption onto the P4VP films. Further, these monolayer surfaces containing GNPs were capped with a bifunctional cross-linker, 1,6-hexanedithiol (HDT). To the additional end termini of HDT, a second layer of GNPs (approximately 20 nm) was assembled. The self-assembly of 1,6-hexanedithiol on the immobilized GNPs and the bilayered architectures were investigated by atomic force microscopy (AFM), filed emission scanning electron microscopy (FE-SEM), and UV-Vis absorption spectroscopy.

Polyaniline-Grafted Reduced Graphene Oxide for Efficient Electrochemical Supercapacitors
Publisher: American Chemical Society (ACS)
Date: 03-02-2012
DOI: 10.1021/NN204688C
Abstract: An alternative and effective route to prepare conducting polyaniline-grafted reduced graphene oxide (PANi-g-rGO) composite with highly enhanced properties is reported. In order to prepare PANi-g-rGO, amine-protected 4-aminophenol was initially grafted to graphite oxide (GO) via acyl chemistry where a concomitant partial reduction of GO occurred due to the refluxing and exposure of GO to thionyl chloride vapors and heating. Following the deprotection of amine groups, an in situ chemical oxidative grafting of aniline in the presence of an oxidizing agent was carried out to yield highly conducting PANi-g-rGO. Electron microscopic studies demonstrated that the resultant composite has fibrillar morphology with a room-temperature electrical conductivity as high as 8.66 S/cm and capacitance of 250 F/g with good cycling stability.

Nitrogen and Sulfur Co‐Doped Hierarchically Porous Carbon Nanotubes for Fast Potassium Ion Storage
Publisher: Wiley
Date: 23-09-2022
Abstract: Exploration of advanced carbon anode material is the key to circumventing the sluggish kinetics and poor rate capability for potassium ion storage. Herein, a synergistic synthetic strategy of engineering both surface and structure is adopted to design N, S co‐doped carbon nanotubes (NS‐CNTs). The as‐designed NS‐CNTs exhibit unique features of defective carbon surface, hollow tubular channel, and enlarged interlayer space. These features significantly contribute to a large potassium storage capacity of 307 mA h g −1 at 1 A g −1 and a remarkable rate performance with a capacity of 151 mA h g −1 even at 5 A g −1 . Furthermore, an excellent cyclability with 98% capacity retention after 500 cycles at 2 A g −1 is also achieved. Systematic analysis by in situ Raman spectroscopy and ex situ TEM demonstrates the structural stability and reversibility in the charge–discharge process. Although the kinetics studies reveal the capacitive‐dominated process for potassium storage, density functional theory calculations provide evidence that N, S co‐doping contributes to expanding the interlayer space to promote the K‐ion insertion, improving the electronic conductivity, and providing le defective sites to favor the K‐ion adsorption.

Progress in Solid Polymer Electrolytes for Lithium‐Ion Batteries and Beyond

Date: 28-09-2021
Abstract: Solid‐state polymer electrolytes (SPEs) for high electrochemical performance lithium‐ion batteries have received considerable attention due to their unique characteristics they are not prone to leakage, and they exhibit low flammability, excellent processability, good flexibility, high safety levels, and superior thermal stability. However, current SPEs are far from commercialization, mainly due to the low ionic conductivity, low Li + transference number ( t Li+ ), poor electrode/electrolyte interface contact, narrow electrochemical oxidation window, and poor long‐term stability of Li metal. Recent work on improving electrochemical performance and these aspects of SPEs are summarized systematically here with a particular focus on the underlying mechanisms, and the improvement strategies are also proposed. This review could lead to a deeper consideration of the issues and solutions affecting the application of SPEs and pave a new pathway to safe, high‐performance lithium‐ion batteries.

Results indicate that the functionalised graphene displays improved performance compared to non-functionalised graphene.

Deep Eutectic Solvents: Green Approach for Cathode Recycling of Li‐Ion Batteries
Publisher: Wiley
Date: 17-10-2021
Abstract: The overarching demand of modern electronics and electrification of transportation has tremendously increased usage of rechargeable lithium‐ion batteries (LIBs). As a result, massive amounts of solid waste are generated from the end‐of‐life LIBs and expected to increase by two‐ to threefolds in the near future. Without proper recycling strategies and infrastructure, the immediate threat of environmental pollution and wastage of resources is clear. One way to circumvent these challenges is to recycle the spent LIBs and recover the components and materials, especially heavy metals for future repurposing applications. This review highlights the recent discoveries on the use of deep eutectic solvents (DESs) as an economical and environmentally friendly medium for metal recovery from spent LIBs. Herein, how the different hydrogen donors and acceptors affect the overall performance of DES in terms of leaching efficiency, time, temperature, and metal recovery rates are outlined. Very importantly, the mechanism of metal leaching from the metal oxides using DES is discussed. Finally, some potential strategies and opportunities for further development of novel DES for metal‐recovery from not only spent LIBs but also other industries such as, mining, oil, and agriculture are outlined.

DOI: 10.1021/ACS.CHEMREV.2C00270
Abstract: Current energy and environmental challenges demand the development and design of multifunctional porous materials with tunable properties for catalysis, water purification, and energy conversion and storage. Because of their amenability to de novo reticular chemistry, metal-organic frameworks (MOFs) have become key materials in this area. However, their usefulness is often limited by low chemical stability, conductivity and inappropriate pore sizes. Conductive two-dimensional (2D) materials with robust structural skeletons and/or functionalized surfaces can form stabilizing interactions with MOF components, enabling the fabrication of MOF nanocomposites with tunable pore characteristics. Graphene and its functional derivatives are the largest class of 2D materials and possess remarkable compositional versatility, structural ersity, and controllable surface chemistry. Here, we critically review current knowledge concerning the growth, structure, and properties of graphene derivatives, MOFs, and their graphene@MOF composites as well as the associated structure-property-performance relationships. Synthetic strategies for preparing graphene@MOF composites and tuning their properties are also comprehensively reviewed together with their applications in gas storage/separation, water purification, catalysis (organo-, electro-, and photocatalysis), and electrochemical energy storage and conversion. Current challenges in the development of graphene@MOF hybrids and their practical applications are addressed, revealing areas for future investigation. We hope that this review will inspire further exploration of new graphene@MOF hybrids for energy, electronic, biomedical, and photocatalysis applications as well as studies on previously unreported properties of known hybrids to reveal potential "diamonds in the rough".

Publisher: World Scientific Pub Co Pte Lt
Date: 10-2008
DOI: 10.1142/S0218625X0801186X
Abstract: Cluster-like network structures of single-walled carbon nanotubes (SWNTs) were synthesized by chemical grafting poly 2-hydroxyethyl methacrylate (polyHEMA) to the sidewalls of SWNTs. Acid chloride-functionalized tubes were coupled with commercially available HEMA monomer, which was in turn polymerized using a radical initiator. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy were used to identify the surface changes on the nanocomposites. Microscopic observations of the nanotube complexes by field emission scanning electron microscopy (FE-SEM) show that the tubes were dispersed and formed cluster-like network, branched structures with less bundling, thus, strongly suggesting a firm coating of the polymer on nanotube walls. The coating was further confirmed by transmission electron microscopy. The thermal properties of the nanotube complex as studied by thermal gravimetric analysis (TGA) revealed that coating enhanced stability of the complex, when compared to that of bulk polyHEMA and pristine SWNTs. The nanotube complexes showed excellent suspension stability when dispersed in organic solvent.

Abstract: Combining hybrid nanostructures of metal nanoparticles (NPs) and carbon nanotubes could afford a novel strategy to prepare promising nanomaterials for the highly sensitive sensors and imaging science applications. Conventional acid oxidation process was used to obtain carboxylic acid bound multi-walled carbon nanotubes (MWNTs) which was further acylated with thionyl chloride to give acyl chloride functionalized MWNTs. Thiol functionalized MWNTs were synthesized by amidation reaction of the acylated MWNTs with cysteamine. Further, gold nanoparticles (GNPs) were successfully fabricated on the tube walls to yield the CNT/ Au hybrid. Fourier transform infrared spectroscopy and energy dispersive X-ray studies were used to characterize the surface chemical functionalities and composition of MWNTs, respectively. Evidence for the attachment of GNPs to thiol functionalized MWNTs was obtained from ultraviolet–visible absorption spectra. In addition, TEM images provided a vivid image of uniform decoration of GNPs on the nanotube sidewalls.

Highly Conducting and Flexible Few-Walled Carbon Nanotube Thin Film
Publisher: American Chemical Society (ACS)
Date: 03-03-2011
DOI: 10.1021/NN103630Y
Abstract: We report an effective route to prepare highly conducting and flexible few-walled carbon nanotube (FWNT) thin films. The free-standing thin films were fabricated by functionalizing FWNTs with 4-ethoxybenzoic acid (EBA) via a direct Friedel-Crafts acylation reaction in a nondestructive polyphosphoric acid hosphorus pentoxide medium. The resulting ethoxybenzoyl-functionalized FWNT (EBA-f-FWNT) was readily dispersible in water. EBA-f-FWNT thin films were formed by a simple suction filtration of the dispersed solution. Electron microscopic studies were employed to characterize the morphologies of the resulting thin films. The obtained results indicate that the structure of FWNTs was not perturbed by the incorporation of EBA moieties, which were uniformly grafted onto FWNTs forming the FWNT networks. Room temperature electrical conductivity of the thin films was obtained using standard four-probe measurements, which revealed a value as high as 29 400 S m(-1), while the tensile strength and modulus of the film were found to be about 80 MPa and 15 GPa, respectively. Cyclic voltammograms revealed a rectangular shape, with superior capacitive behaviors nearing 133 F/g for the thin films, which is very attractive for capacitor applications.

A facile synthesis, antibacterial, and antitubercular studies of some piperidin-4-one and tetrahydropyridine derivatives
Publisher: Elsevier BV

DOI: 10.1016/J.BMCL.2008.10.045
Abstract: The raise in clinical significance of multidrug-resistant bacterial pathogens has directed us to synthesize 2,6-diarylpiperidin-4-one and Delta(3)-tetrahydropyridin-4-ol based benzimidazole and O-arylsulfonyl derivatives. X-ray crystal structure of tetrahydropyridinol (23) confirmed a change in conformation and orientation of substituents upon amide formation. Antibacterial activities evaluated against a wide number of bacterial pathogens (both sensitive and multidrug-resistant) revealed that 19, 27 against Staphylococcus aureus, 27 against Enterococcus faecalis, and 19, 21, 23, and 27 against Enterococcus faecium are significantly good at lowest MIC(90) (16 microg/mL). Inhibitory power noticed by 23 against Vancomycin-Linezolid-resistant E. faecalis and 27 against Vancomycin-resistant E. faecium are onefold better than the standard Linezolid and Trovafloxacin drugs, respectively. Moreover, antitubercular activity for the selected compounds against Mycobacterium tuberculosis H37Rv revealed that compounds 23, 24, and 27 expressed onefold improved potency compared to the standard Rif icin drug.

Expeditious Electrochemical Synthesis of Mesoporous Chalcogenide Flakes: Mesoporous Cu2Se as a Potential High‐Rate Anode for Sodium‐Ion Battery
Publisher: Wiley
Date: 29-07-2022
Abstract: Nanostructured copper selenide (Cu 2 Se) attracts much interest as it shows outstanding performance as thermoelectric, photo‐thermal, and optical material. The mesoporous structure is also a promising morphology to obtain better performance for electrochemical and catalytic applications, thanks to its high surface area. A simple one‐step electrochemical method is proposed for mesoporous chalcogenides synthesis. The synthesized Cu 2 Se material has two types of mesopores (9 and 18 nm in diameter), which are uniformly distributed inside the flakes. These materials are also implemented for sodium (Na) ion battery (NIB) anode as a proof of concept. The electrode employing the mesoporous Cu 2 Se exhibits superior and more stable specific capacity as a NIB anode compared to the non‐porous s les. The electrode also exhibits excellent rate tolerance at each current density, from 100 to 1000 mA g −1 . It is suggested that the mesoporous structure is advantageous for the insertion of Na ions inside the flakes. Electrochemical analysis indicates that the mesoporous electrode possesses more prominent diffusion‐controlled kinetics during the sodiation–desodiation process, which contributes to the improvement of Na‐ion storage performance.

Publisher: American Chemical Society (ACS)
Date: 18-12-2019
Abstract: The shuttling phenomena in lithium-sulfur batteries lead to drastic attenuation of the capacity. This can be suppressed effectively by modifying the separator. Herein, a double-layered separator composed of a macroporous polypropylene (PP) matrix layer and an arrayed poly(methyl methacrylate) (PMMA) microsphere retarding layer is designed as the separator for lithium-sulfur batteries. A sulfur positive electrode with the PP/PMMA separator exhibits a high initial capacity of 1100.10 mAh g
