Abstract:
This review focuses on our research findings about efficiency of different nano materials synthesized by us for photocatalytic hydrogen production from industrial wastes. Lab-scale photocatalytic reactors were fabricated for hydrogen production from liquid phase alkaline waste streams and gaseous phase hydrogen sulfide. The effects of operating parameters namely pH, flow rate, light intensity, liquid depth, sulfide and sulphite concentration were investigated for for 7 photocatalysts viz., CuGa2-xFexO4/RuO2, Fe2O3-CdS/ZnS, Pd-Cr2O3/CdS, Ce-TiO2, CdS-ZnS/TiO2, CdS/ZnS, Ti-Cr-MCM-48. Among the photocatalysts used, CdS/ZnS nanosized photocatalyts have a much greater surface area and thus give a better hydrogen yield.
