Abstract

Abstract An effective technique for improving the photocatalytic activity is the functional‐group‐oriented approach of covalent organic frameworks (COFs). However, the creation of the functional groups‐dependent COF‐based S‐scheme heterojunction has seldom been reported. In this study, two distinct Tp‐based COFs with different functional groups using a solvothermal technique, TpPa‐1 with −H and TpPa‐2 with −Me (methyl), respectively, is synthesized. Moreover, functional groups‐dependent Tp‐based COF/MgIn 2 S 4 (MIS) S‐scheme heterojunctions (i.e., TpPa‐1/MIS and TpPa‐2/MIS) are created to clarify the dynamics of photoinduced charges and boost the photocatalytic H 2 evolution. Notably, the photocatalytic H 2…
