A novel nanostructured semiconductor photocatalyst for solar hydrogen production

In view of this, we investigated new visible light nanostructured semiconductor photocatalyst especially in the field of composite metal oxide photocatalyst for solar hydrogen production from H2S. For this purpose, two methodologies using a quantum mechanical material design and the microscopic surface analysis on a nanometer scale are adopted. The catalysts are synthesized by our proprietary soft chemical approaches. Also, a demonstrative reaction system for the effective solar hydrogen production is presented.
