Abstract

Design and construction of semiconductive heterostructures is an efficient strategy for expanding the range of absorption spectra, and thus enhancing the photocatalytic activity. With TiO₂ nanofibers as a starting point, one-dimensional CeVO₄/TiO₂ heterostructures have been controllably synthesized via electrospinning and post solvothermal route. The introduction of CeVO₄ nanorods slantwise grown on the surface of TiO₂ nanofibers is in favor of efficient separation of photogenerated charges. Furthermore, the microstructures and photocatalytic properties of hierarchical CeVO₄/TiO₂ are characterized in detail. Compared with individual CeVO₄ and TiO₂ nanomaterials, one-dimensional hierarchical CeVO₄/TiO₂ heterostructures possess the extraordinary photocatalytic properties under simulated sunlight irradiation, which was demonstrated by the photocatalytic degradation rates of NB (93.1%) and RhB (94.5%).
