A core-shell nanowires of SnO2 and single-walled carbon nanotubes (SnO2/SWCNTs) was synthesized by electrodeposited technique. The morphology and microstructure of the as-prepared composites were characterized by Scanning Electron Microscopy, High-resolution transmission electron microscopy, Raman microscope, and X-ray diffraction. The characterizations indicate that SnO2 successfully deposited on SWCNTs surfaces. The electrochemical performance of the core-shell structures as electrode materials of supercapacitor was investigated. The results showed that SnO2/SWCNTs core-shell nanowires have much higher specific capacitance of 320 F.g− 1, at a scan rate of 6 mV.s− 1 and excellent cycling capability. Our results demonstrate that these core-shell nanowires are very promising for supercapacitors application.
