Self-assemble SnO2@TiO2 porous nanowire–nanosheet heterostructures for enhanced photocatalytic property

Abstract

One-dimensional semiconductor heterostructures with unique properties are suited to application in the photocatalysis field. In this study, rationally designed SnO₂@TiO₂ porous nanowire–nanosheet heterostructures were realized by a facile hydrothermal method via loading TiO₂ nanosheets onto SnO₂ porous nanowires. One-dimensional porous heterostructures formed via the self-assembly process. Due to the improved photon absorption ability and more active sites, the special heterostructures showed enhanced photocatalytic properties under mixed light, nearly 2.5 times faster than that of SnO₂ porous nanowires. Our results suggest that the SnO₂@TiO₂ porous nanowire–nanosheet heterostructures are promising as photocatalysts.
