Carbon-coated SnO2 nanotubes: template-engaged synthesis and their application in lithium-ion batteries

Nanoscale. 2011 Feb;3(2):746-50. doi: 10.1039/c0nr00716a. Epub 2010 Nov 29.

Abstract

This paper reports the synthesis of carbon-coated SnO2 (SnO2-C) nanotubes through a simple glucose hydrothermal and subsequent carbonization approach by using Sn nanorods as sacrificial templates. The as-synthesized SnO2-C nanotubes have been applied as anode materials for lithium-ion batteries, which exhibit improved cyclic performance compared to pure SnO2 nanotubes. The hollow nanostructure, together with the carbon matrix which has good buffering effect and high electronic conductivity, can be responsible for the improved cyclic performance.
