Graphdiyne (CnH2n−2) coupled with ZnCo-MOF double S-scheme heterojunction forms an efficient electron transport layer and its characterizationvia in situXPS

The catalyst constructs double S-scheme heterojunctions. The excellent electrical conductivity of GDY and the synergistic effect of S-scheme heterojunctions promote the charge transfer and significantly improve the photocatalytic hydrogen evolution activity of GDY.
