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 .
对一系列金/二氧化钛光催化剂产氢的研究表明，金纳米颗粒根据光照射的波长发挥不同作用。在可见光照射下，光活性主要由金表面等离子体激元带的强度控制，而在紫外光照射下，金纳米颗粒与二氧化钛一起作为助催化剂。
