Hydrogen production by graphdiyne (CnH2n−2)-based graphdiyne/CuI/NiMn(LDHs) double S-scheme heterojunctions

CuI–GDY was prepared by cross-coupling method, and CuI–GDY/NiMn(LDHs) composite catalysts were prepared by a simple solvothermal method, and the constructed double s-type heterojunction accelerated the electron transfer rate.
