MOF-templated formation of porous CuO hollow octahedra for lithium-ion battery anode materials

Porous CuO hollow architectures with perfect octahedral morphology are synthesized simply by annealing Cu-based metal–organic framework (MOF) templates. When tested as anode materials for lithium-ion batteries, these hollow octahedra exhibit greatly enhanced performance of lithium storage with excellent cycling stability and good rate capability.
