Small, Journal Year: 2023, Volume and Issue: 19(48)

Published: Aug. 4, 2023

Abstract Covalent organic frameworks (COFs) are one type of porous materials linked by covalent bonds. COFs exhibit many outstanding characteristics such as high porosity, chemical and thermal stability, large specific surface area, efficient electron transfer efficiency, the ability for predesigned structures. These exceptional advantages enable to remarkable performance in photocatalysis. Additionally, activity photocatalysts can be significantly upgraded ion doping formation heterojunctions. This paper summarizes latest research progress on COF‐based applied photocatalytic systems. Initially, typical structures preparation methods analyzed compared. Moreover, essential principles reactions over COFs‐based developments hydrogen production, CO 2 reduction, pollutants elimination, transformation, overall water splitting indicated. At last, outlook challenges photocatalysis discussed. review is intended permit instructive guidance use based future.

Asymmetric Atomic Dual‐Sites for Photocatalytic CO₂ Reduction

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(38)

Published: July 23, 2024

Abstract Atomically dispersed active sites in a photocatalyst offer unique advantages such as locally tuned electronic structures, quantum size effects, and maximum utilization of atomic species. Among these, asymmetric dual‐sites are particular interest because their charge distribution generates local built‐in electric potential to enhance separation transfer. Moreover, the dual provide flexibility for tuning complex multielectron multireaction pathways, CO 2 reduction reactions. The coordination opens new possibilities engineering structure–activity–selectivity relationship. This comprehensive overview discusses efficient sustainable photocatalysis processes photocatalytic reduction, focusing on strategic active‐site design future challenges. It serves timely reference development conversion processes, specifically exploring here exemplified by into valuable chemicals.
