摘要：
The effective conversion of CO2 to useful fuels aids to relieve energy crisis and reduce the risk of climate change. Based on the enhancement of CO2 adsorption ability, Ti4+ ions in SrTiO3 were substituted by transition metal ions with smaller electronegativity, which is helpful to improve the photocatalytic activity of SrTiO3 for CO2 reduction. Among the as-prepared samples doped by Co, Fe, and Ni ions, Co ions doped SrTiO3 displays the most outstanding photocatalytic performance for CO2 photoreduction. Efficiently conversion of CO2 to fuel CH4 could be attained over nanostructured Pt-SrTi0.98Co0.02O3, and the yield of CH4 under visible light irradiation is 63.6 ppm h(-1). It is impressive that the yield of CH4 over Pt-SrTi0.98Co0.02O3 is about 3 times higher than that over Pt-TiO2/N.
