NiO@SiO₂@TiO₂ coaxial trilayered nanocables were successfully fabricated through modified electrospinning equipment via electrospinning technique. The samples were characterized by thermogravimetric-differential thermal analysis (TG-DTA), X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Results showed that the obtained products are NiO@SiO₂@TiO₂ coaxial trilayered nanocables. The core layer is NiO, and its diameter is ca. 40～50 nm. The middle layer is SiO₂, and its thickness is ca. 40～45 nm. The outer layer is TiO₂ and the thickness is about 45～50 nm. Formation mechanism of NiO@SiO₂@TiO₂ coaxial trilayered nanocables was preliminarily proposed.
