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-1HCl.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.
