Smart Solar-Metal-Air Batteries Based on BiOCl Photocorrosion for Monolithic Solar Energy Conversion and Storage
Publisher: Wiley
Date: 07-12-2022
Abstract: Herein, a BiOCl hydrogel film electrode featuring excellent photocorrosion and regeneration properties acts as the anode to construct a novel type of smart solar–metal–air batteries (SMABs), which combines the characteristics of solar cells (direct photovoltaic conversion) and metal–air batteries (electric energy storage and release interacting with atmosphere). The cyclic photocorrosion processes between BiOCl (Bi 3+ ) and Bi can simply be achieved by solar light illumination and standing in the dark. Upon illumination, the device takes open‐circuit configuration to charge itself from the sunlight. Notably, in this system, the converted solar energy can be stored in the SMABs without the need of external assistance. In the discharging process in the dark, Bi 0 spontaneously turns back to Bi 3+ producing electrons to induce the oxygen reduction reaction. With an illumination of 15 min, the battery with an electrode area of 1 cm 2 can be continuously discharged for ≈3000 s. Taking elemental Bi as the calculation object, the theoretical capacity of the SMABs is 384.75 mAh g ‐1 , showing its potential application in energy storage. This novel type of SMABs is developed based on the unique photocorrosive and self‐oxidation reaction of BiOCl to achieve photochemical energy generation and storage.

DOI: 10.1039/C8NR07379A
Abstract: Single-walled carbon nanotubes (SWCNTs) have attracted significant attention due to their outstanding mechanical, chemical and optoelectronic properties, which makes them promising candidates for use in a wide range of applications. However, as-produced SWCNTs have a wide distribution of various chiral species with different properties (i.e. electronic structures). In order to take full advantage of SWCNT properties, highly purified and well-separated SWCNTs are of great importance. Recent advances have focused on developing new strategies to effectively separate nanotubes into single-chirality and/or semiconducting/metallic species and integrating them into different applications. This review highlights recent progress in this cutting-edge research area alongside the enormous development of their identification and structural characterization techniques. A comprehensive review of advances in both controlled synthesis and post-synthesis separation methods of SWCNTs are presented. The relationship between the unique structure of SWCNTs and their intrinsic properties is also discussed. Finally, important future directions for the development of sorting and purification protocols for SWCNTs are provided.

Abstract: Dye-sensitized solar cells (DSSCs) have received significant attention from the scientific community since their discovery in 1991. However, the high cost and scarcity of platinum has motivated researchers to seek other suitable materials for the counter electrode of DSSCs. Owing to their exceptional properties such as high conductivity, good electrochemical activity, and low cost, carbon nanotubes (CNTs) have been considered as promising alternatives to expensive platinum (Pt) in the counter electrode of DSSCs. Herein, we provide a Minireview of the CNTs use in the counter electrode of DSSCs. A brief overview of Pt-based counter electrodes is also discussed. Particular attention is given to the recent advances of counter electrodes with CNT-based composite structures.

Investigation of Al 2 O 3 -MWCNTs hybrid dispersion in water and their thermal characterization
Publisher: American Scientific Publishers
Date: 06-2012
Abstract: Synthesis of water based Al2O3-MWCNTs hybrid nanofluids have been investigated and characterized. Al2O3-MWCNTs nanoparticles in weight proportion of 97.5:2.5 to 90:10 have been studied over 1% to 6% weight concentration. Dispersion quality of nanofluids is assured by additional synthesis process like acids treatment and grinding of MWCNTs by planetary ball mill. The effects of ground and non-ground MWCNTs over dispersion quality and thermal conductivity have been investigated. Sedimentation effect of hybrid nanofluids with time length has been studied by s le visualization and TEM micrographs. The augmentative absorbance and thermal conductivity of hybrid nanofluids have been compared with pure Al2O3/water nanofluids. The overall result shows that the enhancement in normalized thermal conductivity of hybrid nanofluids is still not so sharp though the absorbance and other qualities show much better comparing mono type nanofluids. Hybrid nanofluids with spherical particles show a smaller increase in thermal conductivity comparing cylindrical shape particles.

Green and scalable electrochemical routes for cost‐effective mass production of MXenes for supercapacitor electrodes
Publisher: Wiley
Date: 31-01-2023
DOI: 10.1002/CEY2.295
Abstract: One of the most unique properties of two‐dimensional carbides and nitrides of transition metals (MXenes) is their excellent water dispersibility and yet possessing superior electrical conductivity but their industrial‐scale application is limited by their costly chemical synthesis methods. In this work, the niche feature of MXenes was capitalized in the packed‐bed electrochemical reactor to produce MXenes at an unprecedented reaction rate and yield with minimal chemical waste. A simple NH 4 F solution was employed as the green electrolyte, which could be used repeatedly without any loss in its efficacy. Surprisingly, both fluoride and ammonium were found to play critical roles in the electrochemical etching, functionalization, and expansion of the layered parent materials (MAXs) through which the liberation of ammonia gas was observed. The electrochemically produced MXenes with excellent conductivity, applied as supercapacitor electrodes, could deliver an ultrahigh volumetric capacity (1408 F cm −3 ) and a volumetric energy density (75.8 Wh L −1 ). This revolutionary green, energy‐efficient, and scalable electrochemical route will not only pave the way for industrial‐scale production of MXenes but also open up a myriad of versatile electrochemical modifications for improved functional MXenes.
Graphene-Like Monoelemental 2D Materials for Perovskite Solar Cells
Publisher: Wiley
Date: 12-02-2023
Abstract: Perovskite solar cells (PSCs) have attracted a great deal of attention from the photovoltaic (PV) community because of their remarkable performance, low production cost, and high potential to be integrated into other optoelectronic applications. Despite their promise, the challenges associated with their operational stability have drawn increasing attention over the past decade. Owing to their unique structure and fascinating properties such as high charge mobility, excellent conductivity, tunable bandgap, good optical transparency, and optimal surface functionalization, nanostructured materials, in particular monoelemental 2D materials, have recently been demonstrated to play versatile functions in suppressing the degradation of PSCs and enhancing the PV performance of the devices. In this review, recent advances in perovskite solar cells employing monoelemental 2D materials are presented. A brief overview of perovskite light absorbers based PV devices is first introduced, followed by critical discussions on the use of various elemental 2D materials including graphene, phosphorene, antimonene, borophene, bismuthene, and their derivatives for different components of the perovskite solar cells. Finally, the challenges in this cutting‐edge research area are highlighted, and the authors express their own perspectives on addressing these key issues.

Near‐Infrared Active Lead Chalcogenide Quantum Dots: Preparation, Post‐Synthesis Ligand Exchange, and Applications in Solar Cells
Publisher: Wiley
Date: 21-02-2019
Abstract: Quantum dots (QDs) of lead chalcogenides (e.g. PbS, PbSe, and PbTe) are attractive near-infrared (NIR) active materials that show great potential in a wide range of applications, such as, photovoltaics (PV), optoelectronics, sensors, and bio-electronics. The surface ligand plays an essential role in the production of QDs, post-synthesis modification, and their integration to practical applications. Therefore, it is critically important that the influence of surface ligands on the synthesis and properties of QDs is well understood for their applications in various devices. In this Review we elaborate the application of colloidal synthesis techniques for the preparation of lead chalcogenide based QDs. We specifically focus on the influence of surface ligands on the synthesis of QDs and their solution-phase ligand exchange. Given the importance of lead chalcogenide QDs as potential light harvesters, we also pay particular attention to the current progress of these QDs in photovoltaic applications.

Pt Nanocluster Co-Catalysts for Photocatalytic Water Splitting
Publisher: MDPI AG
Date: 22-11-2018
DOI: 10.3390/C4040064
Abstract: Degussa P25 is a benchmark form of TiO2 used worldwide in photocatalysis studies. Currently, no such benchmark exists for co-catalysts, which are essential for many photocatalytic reactions. Here, we present the preparation of Pt nanocluster co-catalysts on TiO2 using an unmodified commercial source and equipment that is commonly available. Transmission electron microscopy reveals that the procedure produces TiO2 decorated with Pt atoms and nanoclusters (1–5 atoms). Optical reflectance and X-ray diffraction measurements show that the procedure does not affect the TiO2 polymorph or ultraviolet-visible (UV-Vis) absorbance. Gas phase photocatalytic splitting of heavy water (D2O) shows that the Pt nanocluster-decorated TiO2 outperforms Pt nanoparticle (produced by photodeposition) decorated TiO2 in D2 production. Pt nanoclusters, produced directly from a commercial source, with high co-catalyst activity, are prime candidates to be used in benchmark photocatalytic reactions.

Cytomembrane-Inspired MXene Ink with Amphiphilic Surfactant for 3D Printed Microsupercapacitors
Publisher: American Chemical Society (ACS)
Date: 24-08-2022
Abstract: Two-dimensional (2D) material-based hydrogels have been widely utilized as the ink for extrusion-based 3D printing in various electronics. However, the viscosity of the hydrogel ink is not high enough to maintain the self-supported structure without architectural deformation. It is also difficult to tune the microstructure of the printed devices using a low-viscosity hydrogel ink. Herein, by mimicking a phospholipid bilayer in a cytomembrane, the hiphilic surfactant nonaethylene glycol monododecyl ether (C12E9) was incorporated into MXene hydrogel. The incorporation of C12E9 offers hiphilicity to the MXene flakes and produces a 3D interlinked network of the MXene flakes. The 3D interlinked network offers a high-viscosity, homogenized flake distribution and enhanced printability to the ink. This ink facilitates the alignment of the MXene flakes during extrusion as well as the formation of the aligned micro- and sub-microsized porous structures, leading to the improved electrochemical performance of the printed microsupercapacitor. This study provides an ex le for the preparation of microelectronics with tunable microstructures.

1D‐2D Synergistic MXene‐Nanotubes Hybrids for Efficient Perovskite Solar Cells
Publisher: Wiley
Date: 02-07-2021
Abstract: Incorporation of 2D MXenes into the electron transporting layer (ETL) of perovskite solar cells (PSCs) has been shown to deliver high‐efficiency photovoltaic (PV) devices. However, the ambient fabrication of the ETLs leads to unavoidable deterioration in the electrical properties of MXene due to oxidation. Herein, sorted metallic single‐walled carbon nanotubes (m‐SWCNTs) are employed to prepare MXene/SWCNTs composites to improve the PV performance of PSCs. With the optimized composition, a power conversion efficiency of over 21% is achieved. The improved photoluminescence and reduced charge transfer resistance revealed by electrochemical impedance spectroscopy demonstrated low trap density and improved charge extraction and transport characteristics due to the improved conductivity originating from the presence of nanotubes as well as the reduced defects associated with oxygen vacancies on the surface of the SnO 2 . The MXene/SWCNTs strategy reported here provides a new avenue for realizing high‐performance PSCs.

Highly Dispersed Ru Nanoparticles on Boron-Doped Ti3C2Tx (MXene) Nanosheets for Synergistic Enhancement of Electrocatalytic Hydrogen Evolution
Publisher: Wiley
Date: 19-08-2021
Abstract: 2D‐layered materials have attracted increasing attention as low‐cost supports for developing active catalysts for the hydrogen evolution reaction (HER). In addition, atomically thin Ti 3 C 2 T x (MXene) nanosheets have surface termination groups (T x : F, O, and OH), which are active sites for effective functionalization. In this work, heteroatom (boron)‐doped Ti 3 C 2 T x (MXene) nanosheets are developed as an efficient solid support to host ultrasmall ruthenium (Ru) nanoparticles for electrocatalytic HER. The quantum‐mechanical first‐principles calculations and electrochemical tests reveal that the B‐doping onto 2D MXene nanosheets can largely improve the intermediate H* adsorption kinetics and reduce the charge‐transfer resistance toward the HER, leading to increased reactivity of active sites and favorable electrode kinetics. Importantly, the newly designed electrocatalyst based on Ru nanoparticles supported on B‐doped MXene (Ru@B–Ti 3 C 2 T x ) nanosheets shows a remarkable catalytic activity with low overpotentials of 62.9 and 276.9 mV to drive 10 and 100 mA cm −2 , respectively, for the HER, while exhibiting excellent cycling stabilities. Moreover, according to the theoretical calculations, Ru@B–Ti 3 C 2 T x exhibits a near‐zero value of Gibbs free energy (Δ G H* = 0.002 eV) for the HER. This work introduces a facile strategy to functionalize MXene for use as a solid support for efficient electrocatalysts.

Carbon Nanotubes for Dye-Sensitized Solar Cells
Publisher: Wiley
Date: 10-04-2015
Abstract: As one type of emerging photovoltaic cell, dye-sensitized solar cells (DSSCs) are an attractive potential source of renewable energy due to their eco-friendliness, ease of fabrication, and cost effectiveness. However, in DSSCs, the rarity and high cost of some electrode materials (transparent conducting oxide and platinum) and the inefficient performance caused by slow electron transport, poor light-harvesting efficiency, and significant charge recombination are critical issues. Recent research has shown that carbon nanotubes (CNTs) are promising candidates to overcome these issues due to their unique electrical, optical, chemical, physical, as well as catalytic properties. This article provides a comprehensive review of the research that has focused on the application of CNTs and their hybrids in transparent conducting electrodes (TCEs), in semiconducting layers, and in counter electrodes of DSSCs. At the end of this review, some important research directions for the future use of CNTs in DSSCs are also provided.

Integrated Full‐Spectrum Solar Energy Catalysis for Zero‐Emission Ethylene Production from Bioethanol
Publisher: Wiley
Date: 12-2021
Abstract: Ethylene, a hydrocarbon (C 2 H 4 ), is one of the widely used products in the chemical industry. A traditional dehydration method of ethanol to ethylene relies strongly on high‐temperature and high‐pressure process with significant energy consumption. In this regard, producing ethylene from bioethanol through dehydration is a promising and sustainable approach, but, this process under mild conditions results in low yields and poor selectivity. Herein, an integrated solar energy catalytic system driven by only sun energy under ambient conditions is established for the first time for bioethanol dehydration using oxygen‐vacancy‐abundant (O v ) WO 3 coupled with a thin layer of carbon coating (C L ) (WO 3− x @C). A record‐high ethylene selectivity of 98.1% is achieved driven by full solar spectrum without any external power, featuring zero pollution emission nature. In this process, O v acts as a solid acid center, which is the key to initiate the dehydration of ethanol to ethylene via a solar thermal process, while the C L promotes solar thermal synergy, ensuring the high reaction temperature and hot carriers transmission simultaneously. In‐situ infrared spectroscopy and thermodynamic calculations demonstrate a novel proton hydrogen‐mediated catalytic process over WO 3− x @C. This work provides a new opportunity of using full‐spectrum solar energy for catalytic generation of value‐added chemicals.

Application of hole-transporting materials as the interlayer in graphene oxide/single-wall carbon nanotube silicon heterojunction solar cells
Publisher: CSIRO Publishing
Date: 2017
DOI: 10.1071/CH17380
Abstract: Solid-state hole-transporting materials, including the traditional poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), and recently developed 4,4′-(naphthalene-2,6-diyl)bis(N,N-bis(4-methoxyphenyl)aniline) (NAP) and (E)-4′,4‴-(ethene-1,2-diyl)bis(N,N-bis(4-methoxyphenyl)-[1″,1‴-biphenyl]-4-amine) (BPV), have been applied as a hole-transporting interlayer (HTL) for graphene oxide/single-walled carbon nanotube–silicon (GOCNT/Si) heterojunction solar cells, forming a GOCNT/HTL/Si architecture. The influence of the thickness of the HTL has been studied. A new AuCl3 doping process based on bath immersion has been developed and proved to improve the efficiency. With the AuCl3-doped GOCNT electrodes, the efficiency of GOCNT/PEDOT:PSS/Si, GOCNT/NAP/Si, and GOCNT/BPV/Si devices was improved to 12.05 ± 0.21, 10.57 ± 0.37, and 10.68 ± 0.27 % respectively. This study reveals that the addition of an HTL is able to dramatically minimise recombination at the heterojunction interface.
