Abstract
We demonstrated the layer-by-layer synthesis of γ-Fe2O3@SnO2@C porous core–shell nanorods. FeOOH nanorods were first synthesized via a hydrothermal process, and acted as a template for subsequent layer-by-layer deposition. It was indicated that the electrostatic attraction between the charged species may play the key role in the formation of the core–shell nanostructures. When used as an anode material in lithium-ion batteries, γ-Fe2O3@SnO2@C porous core–shell nanorods showed high initial Coulombic efficiency, high reversible capacity, and good cycling and rate performances. The correlation between the structure, composition and electrochemical performance was also discussed.
