| Abstract: | An investigation of hydrogen production with a series of Au/TiO2 photocatalysts reveals that the Au nanoparticles play different roles depending on the wavelength of the light irradiation. Under visible‐light irradiation, the photoactivity is primarily controlled by the intensity of the Au surface plasmon band, whereas under UV irradiation the Au nanoparticles act as co‐catalysts with TiO2. |
