Design of covalent organic framework based heterojunctions to inhibit photogenerated carrier dynamics for ultralow recombination and improved photocatalytic hydrogen production

In this study, the donor-acceptor photocatalyst TT-TPDACOF was synthesized. Co 2 CuS 4 was incorporated to strategically engineer a p–n heterojunction structure and prevent charge carrier recombination. The resulting photocatalyst presents significantly enhanced hydrogen evolution performance.
