Abstract

A new technique for the synthesis of multiphase photocatalysts Cd_1-xZn_xS/ZnS with hydrothermal treatment has been proposed. Photocatalysts were characterized by different techniques including XRD, low temperature N₂ adsorption, and UV-vis spectroscopy. The activity of synthesized photocatalysts was tested in the photocatalytic hydrogen evolution from water solutions of Na₂S/Na₂SO₃ under visible light irradiation (λ = 450 nm). It was shown that the hydrothermal treatment of Cd_0.3Zn_0.7S lead to the formation of multiphase Cd_0.6Zn_0.4S/ZnS and increased the activity by a factor of 8.7. The highest exhibited rate of hydrogen evolution on the composite photocatalyst was 8 mmol g^-1 h^-1.
