Photocatalysis on tio2 surface

WebFeb 25, 2024 · TiO2 was the first metal oxide reported to be capable of photocatalytic water splitting in 1972.34 Since then, there have been many studies on TiO2 and other metal oxide photocatalysts. Thus there are numerous reviews on TiO2 photocatalysis,35–39 and this field continues to receive significant research interest. WebAnisotropic silver nanoplateles were purposefully grown on the surface of TiO2 fibers, in order to determine the impact of silver nanoparticle shape on (1) the generation of hot electrons by the silver, (2) the subsequent transfer of those electrons from the silver into the TiO2, and (3) the photocatalytic behavior of the Ag−TiO2 composite.
