Abstract

[ Ni(CH 3 COO) 2 +PVP]@[SnCl 4 + Ti(OC 4 H 9 4 CH3COOH+PVP] precursor composite cable s ha ve been fabricated through modified electrospinning equipment. NiO@SnO 2 @TiO 2 coaxial trilayered nanocables were obtained by calcination of the relevant Ni(CH 3 COO) 2 +PVP]@[SnCl 4 + Ti(OC 4 H 9 4 CH3COOH+PVP] precursor composite cables . The samples were characterized by use of thermogravimetric differential thermal analysis (TG DTA), X ray diffra ctometry (XRD), Fourier transform infrared spectroscopy (FTIR) FTIR), Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) EDS), and Transmission electron microscopy (TEM). Experimental r esults showed that the core layer is NiO, the middle layer is SnO2 and t he outer layer is TiO 2 Finaly the synthesis mechanism of NiO@SnO 2 @TiO 2 coaxial trilayered nanocables was preliminarily proposed..
