High symmetric porous Co3O4 hollow dodecahedra constructed by nanometer-sized building blocks are rationally synthesized by templating against Co-containing zeolitic imidazolate framework-67. The well-defined hollow structure and highly porous framework render these hollow dodecahedra exhibit high specific capacity, excellent cycling stability and superior rate capability when evaluated as an anode material for lithium-ion batteries.
