摘要：It is a great challenge to convert thermochemically stable CO
2 into value-added products such as CH
4, CH
3OH, CO via utilizing solar energy. It is also a difficult task to develop an efficient catalyst for the reduction of CO
2. We have designed and synthesized noble metal-free photocatalytic nanostructure Ni
2P/CdS and Pt/TiO
2 for conversion of CO
2 to methanol in the presence of sacrificial donor triethylamine (TEA) and hydrogen peroxide. The synthesised catalysts physicochemical properties were studied by using several spectroscopic techniques like; XRD, UV-DRS, XPS, TEM, SEM and PL. Quantification of methanol by GC–MS showed encouraging results of 1424.8 and 2843 μmol g
−1 of catalyst for Pt/TiO
2 and 5 wt% Ni
2P/CdS composites, respectively. Thus, Ni
2P/CdS is a promising catalyst with higher productivity and significant selectivity than in-vogue catalysts.
