Synthesis and formation mechanism of NiO@SnO 2 @TiO 2 coaxial trilayered nanocables by electrospinning technique

[Ni(CH3COO)2+PVP]@[SnCl4+PVP]@[Ti(OC4H9)4+CH3COOH+PVP] precursor composite cables have been fabricated through modified electrospinning equipment. NiO@SnO2@TiO2 coaxial trilayered nanocables were obtained by calcination of the relevant [Ni(CH3COO)2+PVP]@[SnCl4+PVP]@[Ti(OC4H9)4+CH3COOH+PVP] precursor composite cables. The samples were characterized by use of thermogravimetric–differential thermal analysis (TG–DTA), X–ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), and Transmission electron microscopy (TEM). Experimental results showed that the core layer is NiO, the middle layer is SnO2 and the outer layer is TiO2. Finaly the synthesis mechanism of NiO@SnO2@TiO2 coaxial trilayered nanocables was preliminarily proposed.
