CeO2-TiO2 for Photoreduction Of CO2 To Methanol Under Visible Light: Effect Of Ceria Loading

A visible light-driven photocatalyst, CeO2-TiO2 catalyst with different ceria loading was synthesized by impregnation method between TiO2 powder and cerium oxide nanoparticles slurry. The prepared catalyst samples were characterized by X-ray diffraction (XRD), surface area analysis, UV-vis absorp...
