The surface modification with zinc or indium cyanoferrate species was revealed to significantly increase the rate of H-2 evolution on Pt-loaded ZnIn2S4 photocatalyst under visible light in the presence of [Fe(CN)(6)](4-) as an electron donor basically due to the stable redox behavior, in addition to the previously reported cadmium cyanoferrate species. A stepwise modification was found to enable the formation of thin layers of such cyanoferrate on the photocatalyst surface and thereby improve further the rate of H-2 evolution.
