PtCo@N-GNS catalyst and preparation method and application thereof

The invention relates to a PtCo@N-GNS catalyst and a preparation method and application thereof. According to the invention, a zinc metal zeolite imidazole compound is hydrolyzed at room temperature in the presence of Co and Pt, and the catalyst is prepared by combining tubular furnace sintering and other processes. The material has the characteristics that more holes are generated by evaporation of zinc metal, so that more active sites are exposed out of the material. In addition, the cobalt-platinum alloy particles wrapped by the graphene layer can effectively inhibit corrosion of the alloy, and the catalytic stability of the material is further improved. The material is modified on a glassy carbon electrode, through cyclic voltammetry and linear sweep voltammetry tests, the optimal quality activity of oxygen reduction and ethanol oxidation of the material is as follows: the process is simple, the cost is low, the catalytic activity and durability of the catalyst are far higher than those of a comme
