Controllable Synthesis of Bi2WO6 Nanofibrous Mat by Electrospinning and Enhanced Visible Photocatalytic Degradation Performances

Bi2WO6 nanofibrous mat has been successfully synthesized by a simple electrospinning process. TG-DTA, FT-IR, XRD, SEM, and UV-visible diffuse reflectance spectra were used to characterize the mat. The results indicated that the mat was composed of one-dimensional nanofibers, whose diameter was about 300 nm. The one-dimensional nanofibers consisted of Bi2WO6 nanoparticles with diameter 112 nm. Also, the Bi2WO6 nanofibrous mat exhibited excellent visible photocatalytic property in the photodegradation of methylene blue. Meanwhile, the photocatalyst synthesized by electrospinning is helpful for separation and recycling. What's more, the preparation method is suitable for large-scale commercial production. So, the work has great application value in the future.
