Preparation Of Diversified Metal Sulfides/Conductive Polymer Fiber Composites And Its Photocatalytic Performance

We prepared conducting Polymer fibers fiber mats with an electrospinning method.Using Xe lamp simulated sunlight irradiation，The photocatalytic performance of thecomposites was investigated in a variety of methods.(1) Polyvinylidene fluoride (PVDF), styrene maleic anhydride copolymer (SMA)was dissolved in acetone and nano-graphite and N, N-dimethylacetamide solution,prepared electrospinning fluid. A polymer fiber membrane obtained by using highpressure equipment electrospinning. Cd0.8Zn0.2S, Cd0.8Zn0.2S, CdIn2S4, Co-dopedCdIn2S4nanoscale particles load on micro fiber surface by hydrothermalcoprecipitation method. Scanning electron microscopy (SEM) and X-ray diffraction(XRD) showed that the surface of the conductive polymer successful load loadCd0.8Zn0.2S, CdIn2S4, Co-doped CdIn2S4particles in fiber membrane surface. GetCd0.8Zn0.2S/conductive plymer fiber composites, CdIn2S4/conductive plymer fibercomposites, Co-doped CdIn2S4/conductive plymer fiber composites.(2) The use of a scanning electron microscope (SEM) and X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TG),UV-visible absorption spectroscopy (UV-Vis), transmission electron microscopy(TEM), and other testing methods for composite materials characterization.Theresults show that Cd0.8Zn0.2S, CdIn2S4, Co-doped CdIn2S4particles can successfullyload on the surface of the conductive fiber membrane.The spectra of UV-Visabsorption indicated that the three materials corresponding in the visible range.(3) The use of350W xenon lamps simulate sunlight and three kinds of compositematerials for photocatalytic experiments light at3h. Hydrogen production curve ofCd0.8Zn0.2S/conductive polymer fiber composites show that the rate of hydrogenproduction is210μmol/h.Hydrogen production curve of CdIn2S4/conductive polymerfiber composites show that the rate of hydrogen production is540μmol/h. Thedegradation of Rhodamine B was96.2%. Hydrogen production curve of Co-dopedCdIn2S4/conductive polymer fiber composites show that the rate of hydrogenproduction is350μmol/h. The degradation of Rhodamine B is90.4%.
