  "textContent": "A high-performance positive electrode catalyst for a metal-air battery is disclosed, which is composed of transition metal nitride-transition metal oxide heterogeneous particles and a mesoporous carbon matrix. The nano heterogeneous particles, which are 10-50% based on the total mass of the catalyst, are dispersed in the mesoporous carbon matrix; and the oxide is 10-100% based on the heterogeneous particles. A preparation method of the catalyst includes: treating mesoporous carbon with a strong acid solution to obtain surface-functionalized mesoporous carbon; immersing the surface-functionalized mesoporous carbon in an aqueous solution of a transition metal salt, and stirring and washing; adding ammonia water and stirring to enable a confined complexation reaction; washing again, and vacuum drying; and calcining the product in an inert atmosphere or a vacuum condition.",
