Methods and systems for reproducible technology for the synthesis of a non platinum based palladium-chromium oxide (Pd-Cr203) loaded cadmium sulfide (CdS) photocatalyst (Pd-Cr203/CdS) for solar photocatalytic hydrogen production via an aqueous ammonium sulfite ((NH4)2SO3) solution. This process is one of the important steps in solar driven photo/thermochemical water splitting cycles. The catalyst preparation follows two steps: Firstly, palladium chloride (PdC12) was used as a precursor that was reduced with sodium borohydride (NaBH4) for the preparation of nanosized palladium metal colloid. Secondly, 0.5g of CdS semiconductor powder was 10 added into the Pd colloid to immobilize Pd-Cr203 nanoparticles onto the surface of CdS forming co-catalyst loaded CdS photocatalyst. Results show that the activity of PdICdS is significantly enhanced by Pd and Cr203 nanocomposites loaded Pd-Cr203/CdS photocatalyst.
