COFs‐Based Metal‐Free Heterojunctions for Solar‐to‐Chemical Energy Conversion

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(49)

Published: Aug. 17, 2024

Abstract Covalent organic frameworks (COFs) are a promising class of polymers with the merits robust framework, ultrahigh porosity, and molecularly precise backbones, which reveals great potential for solar‐to‐chemical energy conversion in context mitigating environmental crises. However, photochemical activities individual COFs not as desired, primarily due to their limited light absorption, insufficient dissociation photogenerated excitons readily recombined carriers. Recently, COFs‐based metal‐free heterojunctions synergistic effects provide feasible route boost photocatalytic activity more environmentally friendly cost‐competitive manners. Herein, it is first systematically overview advances from heterojunction types, heterointerfaces interactions, primary design mechanisms. Then, typical photocatalysts (e.g., g‐C 3 N 4 ‐COFs, carbon materials‐COFs, polymer semiconductor‐COFs, COFs‐COFs heterojunction) summarized. Finally, challenges long‐term outlooks future offered terms efficiency, yield, stability, cost reaction mechanisms, well standardized evaluation method activities. It anticipated that this review can deliver new insights into fundamental engineering conversion, further accelerate development area.
