Ag2O/TiO2/V2O5 one-dimensional nanoheterostructures for superior solar light photocatalytic activity.
Titanium dioxide has attracted considerable interest as a prototypical semiconductor photocatalyst. However, because of the relative large bandgap energy, further application of TiO2 photocatalyst is limited by its inefficient solar energy conversion. Various attempts have been made to broaden the light absorption window of the TiO2, such as growth of TiO2-based heterostructures. Herein, a novel three-component system, Ag2O/TiO2/V2O5 one-dimensional nanoheterostructures with enhanced solar light absorption, is prepared by depositing Ag2O nanoparticles onto the surface of TiO2/V2O5 nanofibers through a two-step synthetic process. This three-component system exhibits excellent solar-driven photocatalytic activity, far exceeding those of the single- and two-component systems, as a result of extended solar light absorption and efficient electron-hole separation. Furthermore, the photocatalytic performance of Ag2O/TiO2/V2O5 one-dimensional nanoheterostructures is very stable for recycling use.
