Soft-template assisted synthesis of Fe/N-doped hollow carbon nanospheres as advanced electrocatalysts for the oxygen reduction reaction in microbial fuel cells

Fe and N-co-doped hollow carbon nanospheres have been fabricated via a simple pyrolysis method using poly(aniline-co-pyrrole) copolymer hollow nanospheres as precursors. The resulting catalyst displayed potential application as a cathode in a MFC.
