Using a facile method, a compound (alloy) semiconductor from the family of cadmium-zinc-sulfide doped with tin and silver was hydrothermally synthesized and employed as an efficient photocatalyst to generate hydrogen fuel through a water photosplitting system. X-ray diffraction analyses revealed that the alloy semiconductor is a solid solution that becomes crystalized in a cubic structure, having a smaller lattice constant in the presence of Ag dopant. Reflective UV-visible spectra indicated that the Ag component not only causes the photon absorption to be significantly amplified, but the absorption edge also shows a red shift. Scanning electron microscopy and adsorption/desorption isotherms illustrated that the five-component semiconductor synthesized here belongs to the nanostructured (nanoparticulate/nanoflake) mesoporous materials and exhibits a good photocatalytic performance.
