Abstract
In this work, BiOCl x /BiOBr y /BiOI z (x + y + z = 1) composite nanofibers were prepared through electrospinning and the sol-gel methods. Photocatalytic degradation of trichloroethylene (TCE) by BiOCl x /BiOBr y /BiOI z /PAN nanofibers was systematically investigated via gas chromatography (GC). Optimum photocatalytic activity was achieved with BiOCl 0.3 /BiOBr 0.3 /BiOI 0.4 fibers under solar light irradiation. X-ray photoelectron spectroscopy (XPS) peaks due to C-O and C=O were observed at 286.0 and 288.3 eV, respectively, it indicated that the BiOCl x /BiOBr y /BiOI z mixture had been successfully doped on the polyacrylonitrile (PAN) fibers. Furthermore, X-ray diffraction (XRD) results also confirmed that we had synthesized the as-prepared composite nanofibers successfully. Photocatalytic activities of BiOCl 0.3 /BiOBr 0.3 /BiOI 0.4 were up to 3 times higher than the pure BiOCl, BiOBr and BiOI samples, respectively.
