The authors report the preparation and characterization of (Zn,Cd)S (ZCS) photoelectrodes for hydrogen and oxygen production in a photoelectrolytic cell. ZCS photoelectrodes were prepared by mixing CdS and ZnS powders and sintering at high temperature in the presence of CdCl2, as the flux. In some cases the ZCS was loaded with Mo during the preparation. These mixtures were characterized by structural analysis using X-ray diffraction (XRD), photosensitivity measurements in artificial light (halogen and xenon lamps)in solid state, and in a 0.1 M solution of Na2SO3. The results indicate that a screen printed CdS-ZnS mixture possesses high photosensitivity for its application as photocatalysts for water electrolysis.
