CO2 Photocatalytic Reduction to Solar Fuels Over Platinum/TiO2 and Nickel/TiO2 Heterojunction Under UV Light Irradiation
Keywords:
CO2 Photoreduction, Photodeposition, metal/TiO2Abstract
The photocatalytic reduction of CO2 is an artificial photosynthesis process to produce hydrocarbon fuels by using a semiconductor as photocatalyst. Modification of anatase TiO2 by metal doping (0.04 mol% M/TiO2, M=Pt and Ni) was used in this reaction to enhance the photocatalytic efficiency by photodeposition technique. The materials were characterized by X-ray Absorption Near Edge Spectroscopy (XANE), Transmission Electron Microscope (TEM) and UV-visible diffuse reflectance spectra (UV-DRs). The CO2 photoreduction was conducted in liquid phase under UVA light irradiation. It was found methanol as main product. The presence of metal over TiO2 resulted in enhancement of photoreduction of CO2.
