Abstract

In order to study the photocatalytic effect of tungsten oxide(WO

) and silver/tungsten oxide(Ag/WO

) nanofibers. The WO

and Ag/WO

nanofibers were fabricated by electrospinning method. The crystal phase

morphology and ultraviolet-visible diffuse reflectance spectroscopy of the samples were characterized by X-ray diffraction(XRD)

scanning electron microscopy(SEM) and UV-Vis spectrophotometer(UV-Vis). The photocatalytic degradation performance on Methyl Blue(MB) with WO

and Ag/WO

nanofibers was evaluated under UV-Vis light irradiation. The results demonstrate that the photocatalytic degradation efficiency on MB with Ag/WO

nanofibers is 1.3 times higher than WO

at 90 min. Based on the energy band structure

the principle of photocatalytic efficiency enhancement of Ag/WO

composite fibers was analyzed.
