| Outline of Final Research Achievements |
This research is aimed to synthesize biomolecule / inorganic nanocomposites for the development of a highly efficient H2 production system via water splitting. In the first part, the effect of bacteriorhodopsin (bR) on the photocatalytic hydrogen production over GS/TiO2 has been investigated. The obtained experimental results supported our previously reported mechanism of the H2 output over GS/TiO2. In the second part, biomolecule decorated CdS nanocomposite by solvothermal method. The as-synthesized CdS nanocomposite showed about 18 times higher activity compared to pure CdS in terms of H2 production via water splitting. Improved activity may be attributed to the increased specific surface area of the nanocomposite. These results indicate that nanocomposite of biomolecule/ inorganic compound could be a promising candidate for solar H2 production via water splitting.
