Nanocomposite ZnO/SWNTs of zinc oxide(ZnO) and single-walled carbon nanotubes(SWNTs) were fabricated by a sol-gel method using Zn(CH3COO)2·2H2O as raw material. The samples were characterized by X-ray diffraction spectroscopy, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, Fourier transformed infrared spectroscopy and ultraviolet-visible spectroscopy. The results show that ZnO nanoparticles with the size of about 10 — 20 nm are closely deposit...
