In this paper, flexible polyacrylonitrile (PAN) nanofibers are used as carriers to prepare a one-dimensional bismuth oxyiodide-silver iodide (BiOI-AgI) photocatalyst. PANBiOI- AgI is prepared on the surface of electrospun PAN nanofibers by the alternate growth method and subsequent ion exchange method at room temperature. The results of XRD, TEM, XPS, and UV-Vis diffuse reflectance spectroscopy indicate the heterojunctions formation. The flexible PAN-BiOI-AgI heterojunction fibers show higher photocatalytic degradation efficiency for rhodamine B than PAN-BiOI or PAN-AgI. The enhanced photocatalytic performance is attributed to the fact that the heterojunction improves the photo-generated electron-hole separation efficiency. After 60 min of visible light irradiation, the degradation efficiency is greater than 95%. Free radical capture experiments show that•O2- and h+ are the main groups involved in the oxidation reaction.
