• Note (General): This thesis presents the development of SiC photo-electrodes towards improvement of the solar-to-chemical conversion efficiency and stability for water-splitting and CO2 reduction. The band-edge structure of the 3C-SiC semiconductor analyzed by impedance measurement shows the 3C-SiC has a sufficient potential for the application. However, the dominant obstacles causing unfavorable performance are a high overpotential for water-oxidation reaction and surface corrosion. To overcome these problems, Pt nanoparticles were optimally fabricated on the 3C-SiC surface to promote the carrier transfer at the 3C-SiC/liquid interface. In the viewpoint of durability, the Pt nanoparticles lead to the effect of suppressing the surface oxidation, although the photocurrent still decreases with time. As an approach to the further enhancement of stability, the effect of graphene was investigated as a passivation layer on 3C-SiC. Finally, production of CO gas by the carriers generated from the 3C-SiC photo-anode in aqueous solution was achieved by the CO2 reduction. These results indicate that the 3C-SiC semiconductor is prospective as a photo-electrode for the realization of the artificial photosynthesis system.; identifier:oai:t2r2.star.titech.ac.jp:50265061
