Outline of Final Research Achievements

This study carried out the development of new visible light-driven photocatalyst realizing CO2 Reforming/Recycling as well as H2 Stock at the same time for the system CO2/H2O/H2. Transparent porous fiber (TPF) was selected as a basis and a loaded transition metal and Ps were coated with TiO2 inside the porous of TPF. The aim of this study is to evaluate and improve the high light absorption, CO2 reforming and H2 stock performance of the developed photocatalyst. As a result, the following conclusions have been obtained: (1) CO2/H2O system: It is acknowledged that the CO2 reforming performance of prepared photocatalyst was improved by metal loading. The overlapping effect on CO2 reforming performance was not obtained well. (2) CO2/H2 system, CO2/H2O/H2 system: Though the effect of Fe loading on the CO2 reforming performance improvement was obtained, the effect of H2 addition on the improvement was not obtained.
