SILICON CARBIDE FOR PHOTOCATALYST AND PHOTOCATALYSIS METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve energy conversion efficiency in light irradiation water decomposition of single crystal SiC for photocatalyst.SOLUTION: Single crystal SiC is polished by a diamond grindstone, etc., or is treated by etching using an alkaline solution, etc. after the polishing, so as to achieve surface roughness Ra of 0.1-1.0 μm. The SiC and a counter electrode are made to have contact with each other, and together immersed in an electrolytic solution. Then the SiC is irradiated with light to carry out photocatalysis or photolysis.
