Composite photocatalysts based on Cd_1-x Zn _x S and TiO₂ for hydrogen production under visible light: effect of platinum co-catalyst location.

ABSTRACT: Ternary composite photocatalysts based on titania and solid solutions of CdS and ZnS were prepared and studied by a set of physicochemical methods including XRD, XPS, HRTEM, UV-vis spectroscopy, and electrochemical tests. Two synthetic techniques of platinization of Cd_1-x Zn _x S/TiO₂ were compared. In the first case, platinum was deposited on the surface of synthesized Cd_1-x Zn _x S (x = 0.2-0.3)/TiO₂ P25; in the second one, Cd_1-x Zn _x S (x = 0.2-0.3) was deposited on the surface of Pt/TiO₂ P25. The photocatalytic properties of the obtained samples were compared in the hydrogen evolution from TEOA aqueous solution under visible light (
