Abstract:
We deposited Au nanoparticles as a co-catalyst onto a TiO2 photocatalyst by reducing [AuCl4]- using electrons trapped in the oxygen vacancies of TiO2. The dispersibility and hydrogen production ability of the Au co-catalyst are higher than those prepared using the conventional photodeposition method.
