From the viewpoint of energy and environment, the conversion of CO2 to hydrocarbons by solar energy is the ultimate solution for CO2 emission and renewable energy. The reactions can be summarized as follows: CO2 + 2 H2O → CH4 + 2 O2 CO2 + 2 H2O → CH3OH + 3/2 O2 x CO2 + &frac12; y H2O → CxHy + (x+ 2y) O2 The proposed research comprises catalyst development and practical reactor design, both aiming at highly efficient light harvesting. (1) Professor Jeffrey Chi-Sheng Wu of National Taiwan University (NTU) will synthesize photocatalysts through sol-gel procedures. Novel approaches include various other transition-metals loaded TiO2, such as Cu, Ag and Pt as well as non-titania photo catalysts, such as Ta2O5 and Nb2O5 composite oxides. The steady-state-flow CO2 photo reduction will be carried out in an optical-fiber photo reactor; (2) Professor Guido Mul of Delft University of Technology (DUT) will prepare Ti-based mesoporous catalysts and combine of Cu and Zr, or Cu and Ti inducing visible light catalysts for the CO2 photo reduction. Operando FT-IR and Raman spectroscopy will be used to analyze the dynamics of the surface composition of the catalysts as a function of reaction conditions; (3) Based on the research results of photo catalysts and mechanism of photo reduction from NTU and DUT, both sides will design and improve the photon efficiency of the photo reactors. The final goal is to develop a practical photocatalytic system to convert solar energy to renewable energy.光催化CO2還原碳氫化合物奈米結構材料光反應器PhotocatalysisCO2 reductionhydrocarbonsnanostructured materialsphoto reactors
