Synthesis of NiP/CdS and Pt/TiO nanocomposite for photoreduction of CO into methanol.

It is a great challenge to convert thermochemically stable CO into value-added products such as CH, CHOH, CO via utilizing solar energy. It is also a difficult task to develop an efficient catalyst for the reduction of CO. We have designed and synthesized noble metal-free photocatalytic nanostructure NiP/CdS and Pt/TiO for conversion of CO to methanol in the presence of sacrificial donor triethylamine (TEA) and hydrogen peroxide.
