Abstract: A new technique for the synthesis of multiphase photocatalysts Cd1-xZnxS/ZnS with hydrothermal treatment has been proposed. Photocatalysts were characterized by different techniques including XRD, N2 adsorption, and UV-vis spectroscopy. The activity of the photocatalysts was tested in the photocatalytic H2 evolution from water solutions of Na2S/Na2SO3 under visible light irradiation (λ = 450 nm). It was shown that the hydrothermal treatment of Cd0.3Zn0.7S lead to the formation of multiphase Cd0.6Zn0.4S/ZnS and increased the activity by a factor of 7.5 whereas the deposition of the noble metals on the surface of Cd0.3Zn0.7S increased the activity by a factor of five. The highest rate of H2 evolution on the composite photocatalyst was 7 mmol g1h-1. The deposition of gold on the surface of Cd0.6Zn0.4S/ZnS leads to the further activity increase: the achieved photocatalytic activity and quantum efficiency (450 nm) for 1%Au/Cd0.6Zn0.4S/ZnS were 23 mmol g1h-1 and 34%, respectively.
