Ternary Metal–Organic Framework Derived 2D Fe2O3/Co3O4/NiO/NC Heterostructured Nanosheets for Super Lithium Storage

Fe2O3/Co3O4/NiO/NC nanosheets have been successfully prepared via a two-step annealing process of ternary metal coordination polymer. Attributing to the synergistic effects of the multiple metal oxides and the unique 2D nanosheet structure, the improved electrical conductivity and effective electron/ion transfer enables Fe2O3/Co3O4/NiO/NC electrode to exhibit excellent electrochemical properties with outstanding rate capacity and cycling stability. This work may pave the way to construct ternary metal oxide electrode material with an excellent electrochemical performance by introducing multiple metal oxides.
