abstract = {Single atom catalyst is of great importance for the oxygen reduction reaction (ORR). However, facile preparation of single atom catalyst without using well-designed precursors or labor-intensive acid leaching remains an urgent challenge. Herein, a simple pyrolysis of Fe3+-loaded mesoporous phenolic resin (mPF)-melamine precursor is used to prepare the single atom iron-anchored N-doped mesoporous graphitic carbon nanospheres (Fe/N-MGN). Investigation of the synthesis reveals the appropriate Fe-assisted catalysis effect and mPF template effect, which not only spurs the highly graphitic porous framework of Fe/N-MGN with plentiful pyridinic N/graphitic N, but also assures the dispersed single atom Fe anchoring without elaborated procedures. As a result, the as-synthesized Fe/N-MGN demonstrates high catalytic activity, good durability and excellent methanol tolerance for ORR. This work promises a facile method to regulate the graphitic carbon growth and single atom Fe loading for the highly efficient electrocatalysis.}
