Abstract

A ferromagnetic three-dimensional ordered macroporous TiO₂/CoPt/α-Fe₂O₃ (3DOMTCF) nanocomposite was synthesized via a sol–gel approach templated by poly(methyl methacrylate) (PMMA) microspheres. After magnetization, it exhibited an extremely high reversible capacity and a long cycle life, which were ascribed to the internal magnetic field for reusing pulverized active materials and its unique structure.
