Title:
METAL-CARBON COMPOSITE CATALYST, PREPARATION METHOD THEREFOR, AND ZINC-AIR BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/075906
Kind Code:
A1
Abstract:
A method for preparing a metal-carbon composite catalyst comprises the steps of: preparing a source material comprising a metal precursor and a monomer, which comprises a methylpyrrolidone (NMP); heat treating the source material so as to prepare an intermediate; and carbonizing the intermediate so as to prepare a carbon nanocatalyst in which the metal of the metal precursor is coupled to a carbon matrix structure, wherein, according to whether the source material comprises an organic additive, the type of organic additive, and the type of metal precursor, the carbon matrix structure has a carbon sheet structure and/or a carbon porous body structure, and the metal can be metal ions and/or metal particles. The metal-carbon composite catalyst can have high ORR and OER characteristics, and thus can be used as a cathode material for a zinc-air battery.
