Abstract

A facile and scalable step-wise approach has been developed to fabricate graphene-based TiO₂/SnO₂ hybrid nanosheets (TiO₂@SnO₂@GN). With uniform staggered distribution of rutile SnO₂ and TiO₂ nanocrystals in a 2D mesoporous manner, TiO₂@SnO₂@GN with low content of graphene (∼5 wt%) manifests superior reversible capacity and excellent rate capability as an anode material in lithium-ion batteries.
