Photocatalytic reduction of CO2 into methanol over Cu–Ni–TiO2 supported on SiO2-Al2O3 catalyst

The photocatalytic reduction of carbon dioxide into hydrocarbon over bimetallic-loaded TiO2 supported on SiO2-Al2O3(Ni–Cu–TiO2/SiO2-Al2O3) catalyst was studied. The study also compared the performance of the catalyst with Degussa P25 (TiO2), prepared TiO2, SiO2-Al2O3 loaded with TiO2. The investigat...
