摘要：
Heterostructured SnO2/TiO2 composite nanofibers were prepared via electrospinning fabrication of anatase nanofibers by adopting polyvinylpyrrolidone(PVP) and n-butyl titanate as precursors and hydrothermal growth of SnO2 nanostructures on anatase nanofibers substrate. The morphology and structure of SnO2/TiO2 composite nanofibers were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy(EDX), transmission electron microscopy(TEM) and X-ray diffraction(XRD) analysis. The results showed that SnO2 nanoparticles could evenly grow on the TiO2 nanofibers surface and thus heterostructured SnO2/TiO(2)composite materials were successfully obtained. By employing rhodamine B degradation as the model reaction, the SnO2/TiO2 heterostructures showed enhanced photocatalytic efficiency compared with the bare TiO2 nanofibers under UV light irradiation. The mechanism for the enhancement of photocatalytic activity of heterostructured nanofibers was also discussed.
