Abstract

A method includes the following steps: a first step: the material containing heteroatom and graphite powder are mixed for a preset time by grinding, and the molar ratio of heteroatom to carbon atom is 1%-10%, then the heteroatom precursors are obtained; a second contact step: the heteroatom precursor is filled into a graphite rod with holes and compacted, then the graphite rod is dried for a preset time to obtain a plasma anode and using a DC arc plasma device to prepare the graphite anode into heteroatom-doped CNHs; a third contact step: the heteroatom-doped CNHs are dispersed in a reducing solution, a platinum salt is added to stir evenly, the reduction reaction is carried out by heating and stirring, and after centrifugation, washing and drying, a catalyst with platinum loading is obtained.
