Metal–Organic Frameworks as Photocatalysts for Solar-Driven Overall Water Splitting

Chemical Reviews, Journal Year: 2022, Volume and Issue: 123(1), P. 445 - 490

Published: Dec. 12, 2022

Metal–organic frameworks (MOFs) have been frequently used as photocatalysts for the hydrogen evolution reaction (HER) using sacrificial agents with UV–vis or visible light irradiation. The aim of present review is to summarize use MOFs solar-driven targeting overcome current efficiency limitations in overall water splitting (OWS). Initially, fundamentals photocatalytic OWS under solar irradiation are presented. Then, different strategies that can be implemented on adapt them photocatalysis discussed detail. Later, most active reported until now HER and/or oxygen (OER) critically commented. These studies taken precedents discussion existing sunlight requirements met at large scale also discussed. last section this provides a summary state field and comments future prospects could bring closer commercial application.

Interfacial Chemical Bond and Oxygen Vacancy‐Enhanced In₂O₃/CdSe‐DETA S‐scheme Heterojunction for Photocatalytic CO₂ Conversion

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(23)

Published: March 2, 2023

Abstract The S‐scheme heterojunctions have great potential for photocatalytic carbon dioxide reduction due to their unique carrier migration pathways, superior separation efficiencies, and high redox capacities. However, the precise process of oriented powerful electron transport remains a challenge. Herein, an InOCd bond‐modulated heterojunction In 2 O 3 /CdSe‐DETA is synthesized by simple microwave‐assisted hydrothermal method accelerated photogenerated transfer. Meanwhile, oxygen vacancies (Vo) capture effect. Consequently, thanks synergistic effect this In‐Vo‐In‐O‐Cd structural units at interface, electrons are extracted rapidly transferred surface‐active sites, which improves electronic coupling CO . This finding precisely adjusts transfer pathway shortens distance. chemical bond established in heterostructure with (Vo‐In ) provides new insights into reduction.

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 62(5)

Published: Nov. 1, 2022

Abstract As a consequence of rapid industrialization throughout the world, various environmental pollutants have begun to accumulate in water, air, and soil. This endangers ecological environment earth, remediation has become an immediate priority. Among techniques, piezocatalytic which uniquely take advantage piezoelectric effect, attracted much attention. Piezoelectric effects allow pollutant degradation directly, while also enhancing photocatalysis by reducing recombination photogenerated carriers. In this Review, we provide comprehensive summary recent developments techniques for remediation. The origin effect as well classification materials their application are systematically summarized. We analyze potential underlying mechanisms. Finally, urgent problems future development discussed.

Published: Sept. 2, 2022

S-scheme photocatalysts have demonstrated great potential in solar fuel production. To study the electron transfer pathways heterojunctions, situ irradiated X-ray photoelectron spectroscopy (ISIXPS) is an effective and widely used technology. However, mechanism of ISIXPS identifying heterojunction has not yet been elucidated. In this Perspective, development process formation are first introduced. Afterward, principles XPS measurements thoroughly explained, applications confirming interfacial heterojunctions discussed. Finally, suggestions for future research on utilization proposed. This Perspective will provide deep insight into through ISIXPS.
