Title: Photocatalytic reduction of CO2 gas over TiO2 thin films

Abstract:

conversion of CO₂ to value-added fuels or chemical products by direct use of sunlight is an appealing but a defying process. CO₂ is a rather inert compound and its conversion to other carbon compounds is commonly thermodynamically unfavorable. It is infamous that the efficiencies of photocatalytic reduction  of CO₂ reported so far are very low. This exterimely overwork problem in product identification and quantification. In our work, TiO₂ thin-films were prepared by sol-gel method and characterized by different physicochemical investigations as X-Ray diffraction (XRD), high resolution transmission electron microscopy (TEM), N₂ adsorption- desorption isotherm and FT-IR. The prepared thin films were used in photo-reduction of CO₂ in presence of water vapor at 80ᵒC using gas flow reactor.  TiO₂ showed  high efficiency using UV light.
