Abstract

TiO2(B)@SnO2/carbon hybrid nanowires have been synthesized by two simple hydrothermal processes and subsequent heat treatment in argon. The composite has a unique architecture, as its morphology consists of particles having a TiO2(B) nanowire core and a porous SnO2/carbon nanoparticle shell layer. The unique core/shell structure and chemical composition will be useful for many potential applications, including the lithium ion battery. The electrochemical results on the composite are presented to demonstrate the superior cycling performance and rate capability of the TiO2(B)@SnO2/carbon nanowires. This composite exhibits a high reversible capacity of ∼669mAhg−1, and excellent cycling stability, indicating that the composite is a promising anode material for Li-ion batteries.
