| titleOfInvention | Double-functional oxidation electrocatalyst and preparation method thereof |
| abstract | The invention provides a preparation method of a bifunctional oxidation electrocatalyst, which is a graphene-like carbon nanosheet bifunctional catalyst prepared by controllably synthesizing cobalt-nickel bimetallic oxide nanoparticles coated with carbon shells by a simple one-step pyrolysis method. The graphene-like sheet nano layer and the graphitized carbon shell provide an electron transmission channel for the cobalt-nickel oxide nano particles, and the electron transmission resistance in the reaction process is reduced. Mesopores (about 3nm) distributed on the three-dimensional graphene-like nanosheets and the carbon shell provide channels for material exchange between the electrolyte solution and the nanoparticles, and the material transport capability of the cobalt-nickel oxide is enhanced. The graphite carbon shell reduces the Oswald ripening effect, and makes the cobalt nickel oxide more stable in the dual-function catalysis. The synergistic effect of the cobalt nickel oxide nanoparticles with the diameter of 30-50nm and the nitrogen-doped graphitized carbon shell which are uniformly distributed on the surface of the sheet layer brings about more excellent oxygen reduction activity (the half-slope potential is 0.78V), oxygen evolution reaction activity (the initial potential is 1.26V) and methanol tolerance than 20% of Pt/C. |
