Electrospinning Preparation and Visible-Light Photocatalytic Activity of V2O5 Micro-Nanorod

V2O5 micro-nanorods were fabricated via calcining the as-synthesized precursors prepared by electrospinning technique route using NH4VO3 and PVP as regent. The physicochemical properties of the catalysts were characterized by Thermogravirrietfic and Differential thermal analysis (TG-DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (FE-SEM), X-ray photoelectron spectiosdopy (XPS) and UV-Vis diffuse reflectance spectra (UV-Vis). The photocatalytic activity of V2O5 micronanorod tbWard the decomposition of Methylene Blue (MB) was investigated. The results indicated that calcination temperature had a great influence on the morphologies and crystalline phases of the micro-nanorod. 550 degrees C micronanoroa exhibited the highest activity for degrading MB under Visible light, and the photocatalytic mechanism of V2O5 micro-nanorod was also presented.
