Characterization and Photocatalytic Activity of CeO2-TiO2 for Photoreduction of CO2 to Methanol under Visible Light

A visible light-driven photocatalyst, CeO2-TiO2 catalyst was synthesized by impregnation method between TiO2 powder and cerium oxide nanoparticles slurry. The prepared catalyst samples were characterized by X-ray diffraction (XRD), UV-vis absorption spectroscopy and photoluminescence spectroscopy (P...
