Abstract

Fe-doped Mn_xO_y with hierarchical porosity is prepared from a nanocasting technique using amine-functionalized bromomethylated poly (2,6-dimethyl-1,4-phenylene oxide) (BPPO) membranes as the sacrificial template. The synergistic coupling of a percolating macroporous network, uniformly distributed mesopores, and optimal iron doping is used to improve the electronic and ionic wirings of manganese oxides for Li⁺ storage via the conversion reaction. Very impressive Li⁺ storage capabilities are shown.
