Abstract
We present the synthesis and visible-light-induced catalytic activity of one-dimensional (1D)TiO2/V2O5 branchedheterostructures. The 1D TiO2/V2O5 heterostructures were prepared by RF reactive magnetron sputtering ofV2O5 ontoelectrospun TiO2 nanofibers. Then, the samples were annealed at300 °C for 2 h in air ambientto form the 1D TiO2/V2O5 branched heterostructures. The photodecomposition rate of Rhodamine B (RhB) by the 1DTiO2/V2O5 branched heterostructures under visible light was much faster than that of pureTiO2 nanofibers, revealing that the visible-light-induced catalytic activity of the 1DTiO2/V2O5 branched heterostructures was greatly improved. The enhancement of the photocatalytic activity of the1D TiO2/V2O5 branched heterostructures can be ascribed to the coupling with a small bandgap semiconductor materialV2O5, where the absorption range is extended, the photogenerated electrons and holesare highly separated and the surface charge carrier transfer rate is promoted.
