Outline of Final Research Achievements |
A carbon dioxide (CO2) recycle system utilizing photocatalytic conversion of CO2 to gas fuels such as methane (CH4) was developed. In this system, CH4 can be produced by CO2 photoreduction under deep-ultraviolet light irradiation on an Au-nanoparticle-deposited TiO2 (Au/TiO2) catalyst. We introduced mid-infrared laser irradiation for the excitation of CO2 on the Au/TiO2 catalyst surface in order to improve the CH4 production efficiency. As a result, the CH4 production efficiency can be increased by a factor of 1.7, compared with that without the CO2 excitation. The result of observations of Au/TiO2 catalysts by using a transmission electron microscope suggests that further improvement in the CH4 production efficiency can be obtained by optimizing the deposition of Au nanoparticles on the TiO2 catalyst.
