Abstract

Novel F-CuO and FeOOH hollow octahedra are developed through a facile structure-evolution reaction. The formation of interior voids within the hierarchical octahedra is motivated by the Cl^- ions based etching, under a precise control over reaction agents and conditions. Owing to the synergistic effect of unique structural features and favorable composition, the hollow octahedra exhibit superior lithium-storage properties.

Keywords: CuO; FeOOH; hollow octahedral structures; lithium ion batteries; structure-evolution reaction.
