Complete Photocatalytic Reduction of CO2 to Methane by H-2 under Solar Light Irradiation
Nickel supported on silica-alumina is an efficient and reusable photocatalyst for the reduction of CO2 to methane by H-2, reaching selectivity above 95% at CO2 conversion over 90%. Although NiO behaves similarly, it undergoes a gradual deactivation upon reuse. About 26% of the photocatalytic activity of Ni/silica-alumina under solar light derives from the visible light photoresponse.
