Photoelectrochemical Water Oxidation and Longevous Photoelectric Conversion by a Photosystem II Electrode
Publisher: Wiley
Date: 19-06-2021
Abstract: The immobilization of natural photosystem II (PSII) enzyme onto an artificial electrode offers an ingenious and promising avenue for semiartificial solar energy conversion. However, this process is significantly limited by the poor stability and the short life of PSII. Here, a new prototype of a semiartificial system is reported by anchoring PSII on polyethylenimine‐coated macroporous carbon electrode with a high load. Good electronic communication is established at the biointerface of this PSII electrode, enabling excellent photoelectrochemical (PEC) water oxidation and lasting electricity generation. The maximum turnover number of 10 200 ± 1380 mol O 2 per mol PSII dimer is obtained in this system at around 10 h before complete deactivation, reaching high current‐to‐O 2 conversion efficiencies. The functions of PSII to release O 2 both in light and dark conditions as well as for H 2 O 2 formation are revealed. Under periodic irradiation (AM 1.5G 1 sun), this PSII electrode allows for stable mediated photocurrent output of ≈4.31 µA cm −2 after five days, which represents the most stable photoelectric performance achieved so far for PSII‐related electrodes.

Boosting Fenton-Like Reactions via Single Atom Fe Catalysis
Publisher: American Chemical Society (ACS)
Date: 22-08-2019
Abstract: The maximization of the numbers of exposed active sites in supported metal catalysts is important to achieve high reaction activity. In this work, a simple strategy for anchoring single atom Fe on SBA-15 to expose utmost Fe active sites was proposed. Iron salts were introduced into the as-made SBA-15 containing the template and calcined for simultaneous decomposition of the iron precursor and the template, resulting in single atom Fe sites in the nanopores of SBA-15 catalysts (SAFe-SBA). X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), and extended X-ray absorption fine structure (EXAFS) imply the presence of single atom Fe sites. Furthermore, EXAFS analysis suggests the structure of one Fe center with four O atoms, and density functional theory calculations (DFT) simulate this structure. The catalytic performances of SAFe-SBA were evaluated in Fenton-like catalytic oxidation of

Nitrogen- and Sulfur-Codoped Hierarchically Porous Carbon for Adsorptive and Oxidative Removal of Pharmaceutical Contaminants
Publisher: American Chemical Society (ACS)
Date: 09-03-2016
Abstract: Heteroatom (nitrogen and sulfur)-codoped porous carbons (N-S-PCs) with high surface areas and hierarchically porous structures were successfully synthesized via direct pyrolysis of a mixture of glucose, sodium bicarbonate, and thiourea. The resulting N-S-PCs exhibit excellent adsorption abilities and are highly efficient for potassium persulfate activation when employed as catalysts for the oxidative degradation of sulfachloropyridazine (SCP) solutions. The adsorption capacities of N-S-PC-2 (which contains 4.51 atom % nitrogen and 0.22 atom % sulfur and exhibits SBET of 1608 m(2) g(-1)) are 73, 7, and 3 times higher than those of graphene oxide, reduced graphene oxide, and commercial single-walled carbon nanotube, respectively. For oxidation, the reaction rate constant of N-S-PC-2 is 0.28 min(-1). This approach not only contributes to the large-scale production and application of high-quality catalysts in water remediation but also provides an innovative strategy for the production of heteroatom-doped PCs for energy applications.

DOI: 10.1007/S44246-022-00016-2
Abstract: The accumulation of waste plastics has caused serious environmental issues due to their unbiodegradable nature and hazardous additives. Converting waste plastics to different carbon nanomaterials (CNMs) is a promising approach to minimize plastic pollution and realize advanced manufacturing of CNMs. The reported plastic-derived carbons include carbon filaments (i.e. carbon nanotubes and carbon nanofibers), graphene, carbon nanosheets, carbon sphere, and porous carbon. In this review, we present the influences of different intrinsic structures of plastics on the pyrolysis intermediates. We also reveal that non-charring plastics are prone to being pyrolyzed into light hydrocarbons while charring plastics are prone to being pyrolyzed into aromatics. Subsequently, light hydrocarbons favor to form graphite while aromatics are inclined to form amorphous carbon during the carbon formation process. In addition, the conversion tendency of different plastics into various morphologies of carbon is concluded. We also discuss other impact factors during the transformation process, including catalysts, temperature, processing duration and templates, and reveal how to obtain different morphological CNMs from plastics. Finally, current technology limitations and perspectives are presented to provide future research directions in effective plastic conversion and advanced CNM synthesis.

DOI: 10.1016/J.CHEMOSPHERE.2022.134118
Abstract: Microplastics (MPs) are emerging and recalcitrant micropollutants in the environment, which have attracted soaring interests from a wide range of research disciplines. To this end, numerous technologies have been devised to understand the properties, environmental behaviors, and potential impacts/hazards of MPs. Herein, we present a review on the properties, environmental distribution and possible impacts. In this review, a comprehensive introduction of the most universal types of MPs, their shapes and characters will be first presented. Then the distributions of MPs in the environment and the impacts on microbe, plants, and human will be reported. Finally, major challenges and directions will be discussed to provide some clues to the better understanding, control and migration of MPs pollution in future studies.

Catalysis of a Single Transition Metal Site for Water Oxidation: From Mononuclear Molecules to Single Atoms
Publisher: Wiley
Date: 03-12-2019
Abstract: Low-cost, nonprecious transition metal (TM) catalysts toward efficient water oxidation are of critical importance to future sustainable energy technologies. The advances in structure engineering of water oxidation catalysts (WOCs) with single TM centers as active sites, for ex le, single metallic molecular complexes (SMMCs), supported SMMCs, and single-atom catalysts (SACs) in recent reports are examined. The efforts made on these configurations in terms of design principle, advanced characterization, performances and theoretical studies, are critically reviewed. A clear roadmap with the correlations between the single-TM-site-based structures (coordination and geometric structure, TM species, support), and the catalytic performances in water oxidation is provided. The insights bridging SMMCs with SACs are also given. Finally, the challenges and opportunities in the single-TM-site catalysis are proposed.

DOI: 10.1038/SREP34919
Abstract: In pursuit of lightweighting of automobiles and low emission of transportation, the efforts to develop high-strength, heat-resistant and fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel Al matrix composite with ultrahigh strength reinforced by a three dimensional network of nano-AlN particles for the first time. The in-situ synthesized AlN particles are connected by twinning bonding chains and built up a three dimensional network strengthening Al matrix enormously like the skeleton to human body. The composite containing 16.4wt.% AlN particles shows excellent properties: the ultimate tensile strengths can be up to 518MPa at room temperature and 190MPa at 350 °C. This peculiar performance results from the novel spatial distribution of nano-scale AlN particles. Our findings in this work would help to develop a potential candidate for high-performance heat resistance light-metal based materials.
Functional Carbon Nitride Materials in Photo‐Fenton‐Like Catalysis for Environmental Remediation
Publisher: Wiley
Date: 12-05-2022
Abstract: Among various advanced oxidation processes, coupled photocatalysis and heterogeneous Fenton‐like catalysis (known as photo‐Fenton‐like catalysis) to generate highly reactive species for environmental remediation has attracted wide interests. As an emerging metal‐free photocatalyst, graphitic carbon nitride (g‐C 3 N 4 , CN) has been recently recognized as a promising candidate to catalyze robustly heterogeneous photo‐Fenton‐like reactions for wastewater remediation. This review summarizes recent progress in fabricating various types of CN‐based catalysts for the photo‐Fenton‐like reaction process. Innovative engineering strategies on the CN matrix are outlined, ranging from morphology control, defect engineering, nonmetal atom doping, organic molecule doping to modification by metal‐containing species. The photo‐Fenton‐like catalytic activities of CN loaded with auxiliary sub‐nanoscale (e.g., quantum dots, organometallic molecules, metal cations, and single atom metals) and nanoscale metal‐based materials are critically evaluated. Hybridization of CN with bandgap‐matching semiconductors for the construction of type‐II and Z‐scheme heterojunctions are also examined. The critical factors (e.g., morphology, dimensionality, light absorption, charge excitation/migration, catalytic sites, H 2 O 2 generation and activation) that determine the performance of CN‐based photocatalysts in Fenton‐like catalysis are systematically discussed. After examining the structure–activity relationship, research perspectives are proposed for further development of CN‐based photocatalysts toward more efficient photo‐Fenton‐like reactions and their application in practical water treatment.

Abstract: Porous carbon serves as a green material for efficient wastewater purification by adsorption and advanced oxidation processes. However, a clear understanding of the simultaneous removal of multiple pollutants in water is still ambiguous. Herein, the synergistic effect of adsorption and peroxydisulfate (PS) activation on kinetics and mechanism of removing single and binary antibiotic pollutants, sulfamethoxazole (SMX) and ibuprofen (IBP), from water by biomass-derived N-doped porous carbon was investigated. Our findings suggest that adsorption contributed to efficient removals of SMX/IBP. Comparative quenching experiments and electrochemical analysis demonstrated that hydroxyl (•OH) and sulfate (SO

Progress of Nb-containing catalysts for carbon dioxide reduction: a minireview
Publisher: Springer Science and Business Media LLC
Date: 17-10-2022
DOI: 10.1007/S42864-022-00185-Y
Abstract: Nb-containing catalysts have the potential to catalyze carbon dioxide (CO 2 ) reduction due to their strong surface acidity and CO 2 activation sites. Still, they have not been widely used in the development and design of catalysts due to the theoretical/cost/safety limitations. Related advances have been continuously reported in the literature, demonstrating to some extent the promise of catalytic applications of Nb-containing catalysts in this area. In this minireview, we discuss the structure–activity relationships of Nb-containing catalysts for photo-, electro-, and thermocatalytic reduction of CO 2 . The engineering strategies of Nb-containing catalysts for enhancing the conversion and selectivity of CO 2 reduction are discussed, ranging from Nb doping, noble metal decoration, surface acidity adjustment, oxygen vacancy engineering, and heterojunction construction to Nb or Nb 2 O 5 particle decoration. The theoretical calculation research for the possible reaction paths and product selectivity is also discussed. Finally, the prospects for designing and optimizing Nb-containing catalysts are proposed. With a deep understanding of catalytic activity and reaction mechanism, this minireview is expected to present the optimization of the Nb-containing catalysts for efficient and highly selective CO 2 reduction.
