Abstract

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-SrTi_0.98Co_0.02O₃, 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-SrTi_0.98Co_0.02O₃ is about 3 times higher than that over Pt-TiO₂/N.
