Modification of the surface of Mn0.25Cd0.75S polyhedra with NiB: reducing the surface work function and promoting electron migration for enhanced photocatalytic hydrogen production

NiB is compounded on the surface of Mn 0.25 Cd 0.75 S to bring them into close contact. The photocatalytic hydrogen production rate of 10% NiB/Mn 0.25 Cd 0.75 S is 13.06 mmol g −1 h −1 , which is 3.7 times higher than that of pure Mn 0.25 Cd 0.75 S.
