Fe–N–C endowed with inexpensiveness, high activity, and excellent anti-poisoning power have emerged as promising candidate catalysts for oxygen reduction reaction (ORR). Single-atom Fe–N–C electrocatalysts derived from Fe-doped ZIF-8 represent the top-level ORR performance. However, the current fabrication of Fe-doped ZIF-8 relies on heavy consumption of time, energy, cost and organic solvents. Herein, we develop a rapid and solvent-free method to produce Fe-doped ZIF-8 under microwave irradiation, which can be easily amplified in combination with ball-milling. After rational pyrolysis, Fe–N–C catalysts with atomic FeN₄ sites well dispersed on the hierarchically porous carbon matrix are obtained, which exhibit exceptional ORR performance with a half-wave potential of 0.782 V (vs. reversible hydrogen electrode (RHE)) and brilliant methanol tolerance. The assembled direct methanol fuel cells (DMFCs) endow a peak power density of 61 mW cm⁻² and extraordinary stability, highlighting the application perspective of this strategy.

具有廉价，高活性和优异的抗中毒能力的Fe–N–C已成为有希望的氧还原反应（ORR）候选催化剂。掺铁ZIF-8衍生的单原子Fe–N–C电催化剂表现出最高的ORR性能。然而，目前的Fe掺杂ZIF-8的制造依赖于时间，能量，成本和有机溶剂的大量消耗。本文中，我们开发了一种快速，无溶剂的方法，可以在微波辐射下生产掺铁的ZIF-8，可以与球磨结合轻松放大。经过合理的热解后，获得了具有原子性FeN ₄位的Fe–N–C催化剂，该位点很好地分散在分层多孔碳基质上，具有出色的ORR性能，半波电势为0.782 V（对可逆氢电极（RHE））和出色的甲醇耐受性。组装的直接甲醇燃料电池（DMFC）具有61 mW cm ^-2的峰值功率密度和非凡的稳定性，突出了该策略的应用前景。
