Porous Fe2O3 nanocubes derived from MOFs for highly reversible lithium storage

Abstract

Porous Fe₂O₃ nanocubes composed of fine Fe₂O₃ nanoparticles have been facilely synthesized by simultaneous oxidative decomposition of Prussian blue (PB) nanocubes at high temperature. When evaluated as an anode material for lithium-ion batteries, the as-obtained porous Fe₂O₃ nanocubes manifest high specific capacity (∼800 mA h g⁻¹ at 200 mA g⁻¹) and excellent cycling performance.
