NOVELTY - Preparation of reduced graphene oxide supported iron-based nanoparticle composite electrocatalytic material involves: (1) preparing iron/nitrogen precursor by thoroughly grinding and mixing ferrocene or its derivative and a nitrogen-containing compound in a mass ratio of 1:(3-5); (2) synchronously decomposing and fumigating to prepare composite material precursor by placing prepared graphene oxide aerogel on an upper layer of a fumigation reaction vessel, placing the iron/nitrogen precursor in a lower layer of the reaction vessel, placing the reaction vessel in a high-temperature atmosphere furnace under inert gas protection conditions, introducing inert gas to form an inert atmosphere, heating at a heating rate of 5-10 degrees C/minute to 400-1000 degrees C, heat preserving for 2-6 hours, and then cooling to room temperature in an inert gas atmosphere; and (3) cleaning the composite precursor with strong acid or alkali to remove non-catalytically active substances, and freeze-drying. USE - The method is useful for preparing reduced graphene oxide supported iron-based nanoparticle composite electrocatalytic material (claimed). ADVANTAGE - The method enables simple and large-scale preparation of the reduced graphene oxide supported iron-based nanoparticle composite electrocatalytic material with high electrocatalytic oxygen reduction initial potential of greater than 0.9 V (vs. reversible hydrogen electrode) and half-wave potential of 8.3 V (vs. reversible hydrogen electrode).
