The invention belongs to the technical field of carbon
material chemistry. The invention discloses a superfine M-N-C non-
noble metal carbon-based
oxygen reduction catalyst, and a preparation method and application thereof.
Transition metal basic acetate, N-heterocyclic or
carboxylic acid organic ligands are adopted as reactants, a certain amount of
solvent and
regulator are added, reaction is performed at a certain temperature to obtain a superfine
metal-organic framework material, and the superfine non-
noble metal carbon-based catalyst is obtained through a one-step
carbonization process. Thesuperfine non-
noble metal carbon-based catalyst is used as a catalyst for
hydrogen fuel
cathode oxygen reduction reaction, excellent catalytic activity is obtained, and the activity of the catalyst is superior to that of a commercial
platinum-carbon catalyst; and in addition, the stability and
methanol poisoning resistance of the catalyst in the
oxygen reduction reaction are superior to those ofan existing
platinum-carbon catalyst. The superfine non-noble
metal carbon-based catalyst can be applied to the fields of
hydrogen fuel cells,
metal-air batteries and the like.
