Fullerene-loaded non-noble metal electrocatalyst as well as preparation method and application thereof

The invention belongs to the technical field of electrochemistry, and particularly relates to a fullerene-loaded non-noble metal electrocatalyst and a preparation method and application thereof.The preparation method comprises the following steps that fullerene and pyrazole are dissolved in an organic solvent, and a solution A is prepared; dissolving non-noble metal chloride in ethanol to prepare a solution B; mixing the solution A and the solution B, carrying out oil bath reaction at 150-200 DEG C in a nitrogen atmosphere and under a stirring condition, and then cooling to room temperature; carrying out rotary evaporation concentration on the reaction system to prepare a precursor; and carrying out staged heating heat treatment on the precursor in an inert gas atmosphere. The precursor is prepared by adopting an oil bath-condensation reflux method, a container is uniformly heated in a controllable range, and meanwhile, the loss of reactants is avoided; the metal can promote the stability of fullerene in the
