Heterojunction Engineering of Multinary Metal Sulfide‐Based Photocatalysts for Efficient Photocatalytic Hydrogen Evolution

Advanced Materials, Journal Year: 2023, Volume and Issue: 36(11)

Published: Dec. 2, 2023

Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one owing altered band alignment at interface stronger driving force for charge separation. Traditional binary metal sulfide (BMS)-based heterojunction such as CdS, MoS

Interfacial Mediation by Sn And S Vacancies of p‐SnS/n‐ZnIn₂S₄ for Enhancing Photocatalytic Hydrogen Evolution with New Scheme of Type‐I Heterojunction

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(50)

Published: Aug. 27, 2023

Abstract The construction of interfacial electric field (IEF) in semiconductor heterojunction is great significance boosting photocatalytic hydrogen evolution through efficient separation photogenerated charge‐carriers. However, the exploitation IEF type‐I has not been proposed for designing photocatalysts. Herein, based on density functional theory prediction, p ‐SnS with different work functions modulated by Sn‐vacancy are compounded n ‐ZnIn 2 S 4 containing S‐vacancy to form heterojunction. optimized SnS/ZnIn photocatalyst without co‐catalysts exhibits an impressive rate 22.75 mmol g −1 h , 6.23 times ZnIn . Systematic investigations reveal that Sn‐S bond acts as a transport channel accelerates interface charge‐carriers transfer under promotion originating from significant Fermi level difference. A large difference surface photovoltage signal and achieved effective IEF. new p‐n scheme induced mediation can separate charge‐carriers, retain highly reductive electrons evolution, overcoming disadvantage reduction potential decline typical scheme. This study will afford theoretical basis achievement high‐efficiency modulation.

Published: Feb. 10, 2023

Water pollution caused by the massive use of medicines has significant environmental problems. This work first reports synthesis and characterization Cu7 S4 /CuCo2 O4 (CS/CCO) yolk-shell microspheres via hydrothermal annealing methods, then investigates their photocatalytic performance in removing organic water pollutants. The 10-CS/CCO composite with exhibits highest photodegradation rate carbamazepine (CBZ), reaching 96.3% within 2 h. also demonstrates more than two times higher rates pure (Cu7 ) CS (CuCo2 CCO. outstanding can be attributed to unique structure Z-scheme charge transfer pathway, reducing multiple reflections acting light. These factors enhance light absorption efficiency efficiently photoexcited carriers. In-depth, degradation pathways CBZ are systematically evaluated identification intermediates Fukui index calculation. insights gained from this serve as a guideline for developing low-cost efficient photocatalyst composites structure.
