Photocatalytic properties of SnO2/TiO2 multilayers
Source abstract
Abstract
Photocatalytic properties of SnO 2 /TiO 2 (TiO 2 overcoated with SnO 2 ) heterojunction system were investigated. It was found that some SnO 2 /TiO 2 thin film stacks have photocatalytic activities and their efficiency depends on the photoactivity of the TiO 2 film and also SnO 2 film properties even though the SnO 2 film itself does not have photocatalytic activity. The experimental results revealed that the interface between TiO 2 and SnO 2 acts as a potential barrier for the carriers photo-generated in the TiO 2 and the photo-generated species pass through the SnO 2 overlayer depending on the SnO 2 film characteristics.
