Summary:The invention relates to a preparation method of a nitrogen-oxygen co-doped porous carbon/ferroferric oxide composite material. The method comprises the following steps of (1) weighing certain parts by weight of cyclopentadienyl iron, hexachlorobutadiene and pyridine, adding the cyclopentadienyl iron, the hexachlorobutadiene and the pyridine to a polytetrafluoroethylene reactor tank and mixing; (2) sealing the polytetrafluoroethylene reactor tank, putting the polytetrafluoroethylene reactor tank into a high temperature reactor, tightening a reactor cover, and putting the reactor into an oven to react at 180-220 DEG C for 6-24h; (3) cooling to a room temperature, opening the reactor, putting a product into the oven and drying at 120 DEG C for 6h; and (4) putting a moderate amount of sampleinto the middle part of a quartz tube of a tube furnace, introducing argon, evacuating the air in the tube, slowly heating the tube furnace at a heating rate of 10 DEG C/min, maintaining the temperature for 60-120min, automat
