Abstract
In this study, we design a CdS/Covalent Organic Framework (COF) heterojunction to enhance the photocatalytic H2 evolution. The results demonstrate that the 30% CdS/TTCOF heterojunction exhibits the highest H2 production activity of 21.8 mmol g−1 under visible light, surpassing that of pure CdS and TTCOF by 8.1 and 18.2 times, respectively. Additionally, time-resolved fluorescence decay and steady-state photoluminescence spectra indicate that the enhanced photocatalytic performance of the CdS/TTCOF heterojunction can be ascribed to fast charge carrier transfer between CdS and TTCOF.
