Abstract

High crystallinity triangle hexagonal Mn_0.45Cu_0.05Cd_0.5S was obtained by partial Cu ion exchange treatment on colloidal pristine Mn_0.5Cd_0.5S nanorods. The Mn_0.45Cu_0.05Cd_0.5S nanotriangles exhibited a high hydrogen yield of 147 921 μmol g⁻¹ h⁻¹ under visible light irradiation, about 7.4 times higher than that of pristine Mn_0.5Cd_0.5S.
