Directional and Ultrafast Charge Transfer in Oxygen‐Vacancy‐Rich ZnO@Single‐Atom Cobalt Core‐Shell Junction for Photo‐Fenton‐Like Reaction

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(30)

Published: May 31, 2023

In photosynthesis, solar energy is harvested by photosensitizers, and then, the excited electrons transfer via a Z-Scheme mode to enzymatic catalytic centers trigger redox reactions. Herein, we constructed core-shell Z-scheme heterojunction of semiconductor@single-atom catalysts (SACs). The oxygen-vacancy-rich ZnO core single-atom Co-N4 sites supported on nitrogen-rich carbon shell (SA-Co-CN) act as photosensitizer enzyme-mimicking active centers, respectively. Driven built-in electric field across heterojunction, photoexcited could rapidly (2 ps) from n-type p-type SA-Co-CN shell, finally boosting performance surface-exposed for peroxymonosulfate (PMS) activation under light irradiation. synergies between photocatalysis heterogeneous Fenton-like reaction lead phenomenally enhanced production various reactive oxygen species rapid degradation microcontaminants in water. Experimental theoretical results validate that interfacial coupling with greatly facilitates PMS adsorption reducing enhancing cascade electron processes photo-Fenton-like reaction.

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.
