The invention belongs to the technical field of electrocatalytic materials, and particularly relates to a high-efficiency difunctional electrocatalyst for a zinc-air battery and a preparation method of the high-efficiency difunctional electrocatalyst. The method comprises the following steps: uniformly mixing a zinc source, an iron source, a nickel source, a multi-block polymer and alcohol to obtain a solution A; uniformly mixing an organic ligand and alcohol to obtain a solution B; adding the solution B into the solution A under a stirring condition, stirring until a turbid solution is formed, standing for 20-28 hours at room temperature, washing the obtained product with alcohol, drying and grinding; and carrying out pyrolysis at 800-1000 DEG C for 2.5-3.5 h under the protection of inert gas, and cooling to room temperature to obtain the high-efficiency difunctional electrocatalyst (target product) for the zinc-air battery. The FeNi bimetallic atom loaded high-curvature carbon net catalyst for the zinc-air
