Although the pore structure of FeNC SACs has been widely investigated from a chemical methodology perspective, the role of synthesis process engineering has received much less attention. To address this, high\u2010gravity technology is introduced during the precursor preparation stage to achieve intensive molecular mixing. This approach successfully yields FeNC SACs with a well\u2010defined hierarchical micro\u2010mesoporous structure. The resulting catalyst exhibits a narrower mesopore size distribution (4\u20136\u00a0nm), a higher specific surface area (800.3 m\n                    <jats:sup>2<\/jats:sup>\n                    \u00b7g\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), and a more positive half\u2010wave potential (0.899\u00a0V) for the oxygen reduction reaction (ORR) compared to a reference sample produced in a conventional stirred tank reactor. Density functional theory (DFT) analysis further indicates that the abundant mesopores induce carbon defects, thereby enhancing the intrinsic ORR activity. Moreover, when integrated into a zinc\u2010air battery and an anion\u2010exchange membrane fuel cell, the catalyst delivers high peak power densities of 259.5 and 860 mW\u00b7cm\n
