NOVELTY - Preparing plasma fluorine-doped modified gamma-type graphite monoacetylene carbon material comprises (1) adding calcium carbide and hexabrobromobenzene into a ball milling tank using ball milling method to prepare gamma -type graphitic monoacetylene; and (2) adopting vacuum system and microwave plasma technology, placing the gamma -type graphitic monoacetylene sample prepared by ball milling into a microwave three-dimensional device; where the system is vacuum state; the pressure is less than 1 Pa, reducing the influence of impurities e.g. oxygen in the system; introducing tetrafluoromethane gas in the reaction process; the machine power is 140-160 W, the processing time is 300-1200 seconds. USE - The method is useful for preparing plasma fluorine-doped modified gamma-type graphite monoacetylene carbon material in electrocatalytic reduction of oxygen catalyst material (claimed). ADVANTAGE - The method improves dynamics performance in the catalysis; and has simple process, low instrument device requirement and easy production.
