| 1 | Surface defect engineering of metal oxides photocatalyst for energy application and water treatment显示文摘Despite metal oxides offer excellent characteristics in the field of photocatalysis,they often suffer from charge carrier recombination as well as limited visible response,which indeed reduce the charge kinetics process and ultimately reduce the photocatalytic output.Defect engineering is a sophisticated technique to manufacture defects and alter the geometric structure and chemical environment of the host.The present study provides an all-inclusive outline of recent developments on the classification of metal oxide defects based on the dimensions of a host crystal lattice.Precisely,surface modification of metal oxides through 0D(point),1D(line),2D(planar),and 3D(volume)defects with their subsequent mechanism and impact on photocatalytic performance are presented.By wisely amending the morphology(cores along with the shells)and electronic structure of metal oxide photocatalysts(TiO_(2),ZnO,Bi_(2)O_(3),Fe_(2)O_(4) etc.)through different attuned and veritable approaches,their photocatalytic activity can be substantially improved.Optimal studies on defect engineering not only expose the altered physicochemical features but also modulate the electron-hole pair dynamics,stability,and active radical production for various photoredox reactions.Altered atomic,as well as electronic configuration,facilitated a photocatalyst material to have different optical features,adsorption properties along with improved carrier transfer as well as isolation rate.Thus,the systematic exploration of photocatalytic rudiments of defect rich metal oxide for various applications such as H_(2) evolution,CO_(2) reduction,pollutant degradation,and bacterial disinfection could bring significant research advancement in this field. | Pankaj Raizada Vatika Soni Abhinandan Kumar Pardeep Singh Aftab Aslam Parwaz Khan Abdullah M.Asiri Vijay Kumar Thakur Van-Huy Nguyen | 2021 | Journal of Materiomics2021，7，2： | 4 |

| 3 | Novel Z-Scheme ZnIn_(2)S_(4)-based photocatalysts for solar-driven environmental and energy applications: Progress and perspectives显示文摘Benefiting from strong redox ability,improved charge transport,and enhanced charge separation,Zscheme heterostructures of ZnIn_(2)S_(4) based photocatalysts have received considerable interest to tackle energy needs and environmental issues.The present review highlights the properties of ZnIn_(2)S_(4),which make it a promising photocatalyst,and a suitable combination with oxidation photocatalyst to form Zscheme,leading to improve their photocatalytic properties dramatically.As the central part of this review,various types of Z-scheme heterojunction developed recently based on ZnIn_(2)S_(4) and their application in pollutant degradation,water splitting,CO_(2) reduction,and toxic metals remediation.Some analytical techniques to detect or trap the active radical and study the charge separation and lifetime of charge carriers in these Z-schemes are highlighted.This review offers its readers a broad optical window for the structural architecture of ZnIn_(2)S_(4)-based Z-schemes,photocatalytic activity,stability,and their technological applications.Finally,we discuss the challenges and opportunities for further development on Z-Scheme ZnIn_(2)S_(4)-based photocatalysts toward energy and environmental applications based on the recent progress. | Yogesh Kumar Rohit Kumar Pankaj Raizada Aftab Aslam Parwaz Khan Quyet Van Le Pardeep Singh Van-Huy Nguyen | 2021 | Journal of Materials Science & Technology2021，，28： | 1 |
| 4 | Tailoring S-scheme-based carbon nanotubes(CNTs)mediated Ag-CuBi_(2)O_(4)/Bi_(2)S_(3)nanomaterials for photocatalytic dyes degradation in the aqueous system显示文摘In this study,S-scheme-based hydrothermal synthesis of Ag-CuBi_(2)O_(4)/CNTs/Bi_(2)S_(3)layered composites has been successfully reported.The photo-degradation of toxic dyes,viz.methyl orange(MO),and methylene blue(MB),has been used to examine nanocomposites with varying weight percent of Bi_(2)S_(3)for photocat-alytic activity in the visible range.Among candidates,Ag-CuBi_(2)O_(4)/CNTs/Bi_(2)S_(3)with a 10%loading of Bi_(2)S_(3)outperformed both pure and hybrid composites in photocatalytic activity.For MO degradation,the hybrid composite with 10%Bi_(2)S_(3)loading degrades 7.04 times higher than pristine CuBi_(2)O_(4)and Bi_(2)S_(3)samples,and for MB degradation,it degrades 4.96 times higher than pristine samples.High surface area,less re-combination rate of photogenerated charge carriers,photogenerated carriers faster separation,and high redox ability of Ag-CuBi_(2)O_(4)/CNTs/Bi_(2)S_(3)(10%)are all attributed to the improving photocatalytic perfor-mance.Even after ten cycles,the hybrid composite is chemically stable and reusable.Carbon nanotubes(CNTs)are a transfer bridge in layered structure for electrons because of their coordinated Fermi level between Ag-CuBi_(2)O_(4)and Bi_(2)S_(3).In addition,the scavenger and electron spin resonance(ESR)experiments verified that·O_(2)^(−),·OH,and h+were the important reactive species that successfully facilitated the pho-tocatalytic degradation process to degrade dyes.This study presents a straightforward and economical approach for obtaining a stable semiconductor-based photocatalytic system and a potential technique for future applications. | Vishal Dutta Anita Sudhaik Sonu Pankaj Raizada Archana Singh Tansir Ahamad Sourbh Thakur Quyet Van Le Van-Huy Nguyen Pardeep Singh | 2023 | Journal of Materials Science & Technology2023，，31： | 0 |
| 5 | Sulphur vacancy defects engineered metal sulfides for amended photo(electro)catalytic water splitting: A review显示文摘Vacancy engineering in metal sulfides has garnered enormous attention from researchers because of their outstanding ability to modulate the optical and physiochemical properties of photocatalysts.Typically,in the case of sulfides,the catalytic activity is drastically hindered by the quick reassembly of excitons and the photocorrosion effect.Hence designing and generating S-vacancies in metal sulfides has emerged as a potential strategy for attaining adequate water splitting to generate H_(2) and O_(2) because of the simulta-neous improvement in the optoelectronic features.However,developing efficient catalysts that manifest optimal photo(electro)catalytic performance for large-scale applicability remains challenging.Therefore,it is of utmost interest to explore the insightful features of creating S-vacancy and study their impact on catalytic performance.This review article aims to comprehensively highlight the roles of S-vacancy in sulfides for amended overall water-splitting activity.The photocatalytic features of S-vacancies modulated metal sulfides are deliberated,followed by various advanced synthetic and characterization techniques for effectual generation and identification of vacancy defects.The specific aspects of S-vacancies in refin-ing the optical absorption range charge carrier dynamics,and photoinduced surface chemical reactions are critically examined for overall water splitting applications.Finally,the vouchsafing outlooks and op-portunities confronting the defect-engineered(S-vacancy)metal sulfides-based photocatalysts have been summarized. | Kusum Sharma Abhinandan Kumar Tansir Ahamad Quyet Van Le Pankaj Raizada Archana Singh Lan Huong Nguyen Sourbh Thakur Van-Huy Nguyen Pardeep Singh | 2023 | Journal of Materials Science & Technology2023，，21： | 0 |
