Controlled pyrolysis of MIL-88A to Fe2O3@C nanocomposites with varied morphologies and phases for advanced lithium storage

Carbon-coated α-Fe₂O₃ hollow nanospindles and varied-phase Fe₂O₃@C (γ-Fe₂O₃@C, αγ-Fe₂O₃@C, and α-Fe₂O₃@C) nanobipyramids were prepared by controlling pyrolysis of MIL-88A nanobipyramids at different temperature and time in air or nitrogen, exhibiting advanced lithium storage capacities.
