In this paper, graphene oxide/polyacrylonitrile (GO/PAN) composite nanofibrous membranes were firstly prepared by an electrospinning method. Then, the GO/PAN composite nanofibrous membranes were further transferred to graphene oxides/carbon nanofibrous membranes (GO-CNFs) by a calcination treatment. Following a solvothermal treatment, zinc sulfide (ZnS) nanopartciles were covered onto GO-CNFs to form electrospun carbon nanofibrous membranes loaded with GO/ZnS (GO/ZnS-CNFs). The composition and microstructure of GO/ZnS-CNFs were characterized by ?eld emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Raman and UV–vis diffuse re?ectance spectra analysis. Due to the synergistic effect between photocatalytic acivity of ZnS and excellent adsorption capacity of GO-CNFs, the resultant GO/ZnS-CNFs exhibited excellent photocatalytic activity for oxidation of p-aminotoluene and phenol under mild conditions. The resultant hybrid carbon composite membranes offer the significant advantages, such as low dosage, high catalytic activity, easy recycling and excellent stability.
