Abstract
, which was 2.57 and 240 times those of ZnCdS and GDY, respectively. The S-scheme heterojunction constructed by GDY-P and ZnCdS accelerates the formation of electron-hole pairs, improves the utilization of strongly reduced electrons, and overcomes the self-agglomeration of ZnCdS, ensuring the high hydrogen evolution activity of the binary structure. This work provides a new application paradigm for the construction of S-scheme heterojunctions for hydrogen evolution using new carbon materials in the field of photocatalysis.
