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

Rational design of a TFPB-TRZ COF bearing the small and heteroatom-rich organic node TRZ (triazole moiety) which facilitates the stabilization of the CO intermediate at the imine (–CN–) site of the COF via electron donation from an N-hetero species.
