摘要
The filling strategy of defect engineering and metal-semiconductor based co-catalysts are effective means to improve photo generated electron transfer and enhance photocatalytic performance. Herein, metal nano copper is used to catalyze the coupling of acetylene groups to form metal-graphdiyne, which is introduced into Mn0.3Cd0.7S with anionic filling vacancies. The maximum hydrogen evolution rate can reach 5063.69 umol·g-1. The initial guidance of photo generated electrons is achieved by filling them with heteroatoms. At the same time, the potential barrier formed between metals and semiconductors hinders the recombination of photo generated electrons and holes, once again playing a guiding role in photo generated electrons. Ultimately achieving the goal of improving photocatalytic activity.
