In this study, for the purpose of clarification of mechanism and optimum condition of reforming CO2 into fuel-like species which are CH4, C2H4 and C2H6 with the aid of photocatalyst, the experimental investigation has been carried out. The acrylic tube reactor composed of the ultraviolet (UV) lamp and copper ring coated with TiO2 by the sol-gel and dip-coating technique was used. After filling the mixture of CO2 and saturated vapor into the reactor, UV lamp was illuminated for 48 hours continuously. The effect of the power of UV lamp and the coating number on the amount of produced fuel-like species was examined. As a result, CH4 production is influenced stronger by coating number than by the power of UV lamp. C2H4 concentration is increased with increasing the power of UV lamp and coating number. The reaction scheme of CO2 reforming into fuel-like species has been revealed.
