| Abstract: | Fe2O3@polypyrrole nanotubes (Fe2O3@PPy nanotubes) have been successfully prepared by in-situ polymerization of the pyrrole on the surface of Fe2O3 nanotubes (Fe2O3-NTs), via using L-Lysine as modified surfactant. Hollow PPy nanotubes were also produced by dissolution of the Fe2O3 core from the core/shell composite nanotubes with 1 mol·L?1 HCl. Scanning electron microscopy(SEM), transmission electron microscope (TEM), selective-area electron diffraction (SAED), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy(FT-IR) confirmed the formation of Fe2O3-NTs and Fe2O3@PPy core/shell nanotubes. Its catalytic properties were investigated under the ultrasound. The results of UV-vis spectroscopy (UV) demonstrated Rhodamine B (RhB) can be efficiently degraded by Fe2O3 @PPy nanotubes. |
