applications. [3] Thus, great efforts have been made to obtain high-performance Pt-free electrocatalysts such as Pt-free alloys, metal oxides, and carbon-based catalysts. [4] Among them, metal and nitrogen-codoped carbon (M-N-C) systems have been considered as one of the most promising candidates in place of Pt-based electrocatalysts. [5] Especially, Fe-N-C catalysts have gained a great attention due to their excellent ORR activity in both alkaline and acidic solutions. [6] The Fe-N-C catalysts are generally obtained by pyrolysis of a compound of iron salts, nitrogen-carbon precursors at high temperature. [7] However, such preparation methods often cause heterogeneous morphologies with unequal distribution of active centers toward ORR. [8] Recently, zeolitic imidazole frameworks (ZIFs), a subclass of metal-organic frameworks (MOFs) with versatile surface geometry, large surface area, abundant pores, and N species, have been regarded as suitable precursors to fabricate structure-tailored carbon-based materials. [9] A number of Fe-doped ZIF-derived carbon materials have been reported as effective ORR electrocatalysts. [5,10] To prepare homogenous catalysts, Chen et al. demonstrated a
