| Research Abstract |
This research was carried out for the ambition of decomposing the carbon dioxide gas, which is known as one of the species that cause global warming, utilizing the thermal energy extracted from concentrated solar light. In this decomposition reaction, hydrogen generated by decomposition of water was used. From this research, it was observed that the energy necessary to decompose the water could be reduced significantly by utilizing a reversible reduction-oxidation property of copper and its oxides material system. The potential of extracting hydrogen from water by solar energy was suggested in this research. As a side result, a fabrication technique of a high quality semiconductor cuprite thin film under relatively low temperature was realized.
