A triazole-based covalent organic framework as a photocatalyst toward visible-light-driven CO₂ reduction to CH₄.

ABSTRACT: Solar-light driven reduction of CO₂ to CH₄ is a complex process involving multiple electron and proton transfer processes with various intermediates. Therefore, achieving high CH₄ activity and selectivity remains a significant challenge. Covalent organic frameworks (COFs) represent an emerging class of photoactive semiconductors with molecular level structural tunability, modular band gaps, and high charge carrier generation and transport within the network. Here, we developed a new heterocyclic triazole ring containing COF, TFPB-TRZ, through the condensation reaction between 1,3,5-tris(4-formylphenyl)benzene (TFPB) and 3,5-diamino-1,2,4-triazole (TRZ). The TFPB-TRZ COF with multiple heteroatoms shows suitable visible light absorption, high CO₂ u
