CeO2-TiO2 as a Visible Light Active Catalyst for the Photoreduction of CO2 to Methanol

The performance of CeO2-TiO2 photocatalyst for the photocatalytic reduction of CO2 into methanol was studied under visible light irradiation. The as-prepared catalysts were characterized for their structural, textural and optical properties using X-ray diffraction (XRD), field emission scanning elec...
