摘 要：Polyaniline nanotubes and PANI-ZnO nanocomposites were prepared by the simplified Template-Free method. The experimental results indicated that the average diameter of Polyaniline nanotubes was approximately 150-200 nm. The average crystallite size of ZnO in PANI-ZnO composites was 27 nm. Moreover, the as-prepared samples were characterized by scanning electron microscopy（SEM）, FT-IR spectroscopy（FTIR） and X-ray diffraction（XRD）. Photocatalytic properties of the obtained samples were investigated by the photodegradation analysis of orange II and methylene orange dye. The as-prepared PANIZnO nanocomposites exhibited much higher photocatalytic activity than pure PANI nanotubes. During 2 h photocatalytic courses under UV irradiation, the degradation ratios of Orange II and methyl orange using PANIZnO nanocomposites were 90.3% and 84.5%, respectively. Furthermore, this method can be extended to prepare other organic-inorganic semiconductor composites based composite catalysts.
