Preparation of Photocatalyst-supported Polyacrylonitrile Micro/Nano Composite Fiber Material and Its Photocatalytic Activity


Acomposite photocatalyst, with branch-like BiOI/Bi2WO6 heterojunction deposited on the polyacrylonitrile micro/nano composite fiber(PAN MNCF), was prepared via two step hydrothermal method. The products are characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), photoluminescence(PL) spectra, UV-Vis diffuse reflection spectroscopy(UV-Vis DRS) and time-resolved fluorescence spectra. The PAN/BiOI/Bi2WO6 micro/nano composite fiber(PAN/BiOI/Bi2WO6 MNCF) showed better visible-light photocatalytic performance than PAN MNCF or BiOI/Bi2WO6 powder, probably ascribed to the collective effect between PAN MNCF and BiOI/Bi2WO6 heterojunction. Significantly, the PAN/BiOI/Bi2WO6 MNCF could be easily recycled through filtration method, thus avoiding the secondary pollution.
