▎ 摘　　要

NOVELTY - Cobalt-nitrogen-carbon catalyst comprises negatively charged carbon as carrier, and carbonizes with ligand connected to cobalt to form cobalt-nitrogen-carbon structure. USE - The cobalt-nitrogen-carbon catalyst is useful in technical field of preparation of catalyst materials. ADVANTAGE - The catalyst: has high-dispersion, and good surface properties, which uses mutual binding force of electrostatic adsorption between positively charged cobalt nitrogen carbon precursor and negatively charged carbon carrier; has improved dispersion degree of cobalt-nitrogen-carbon on support and fully utilized adsorption sites of high specific surface support. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparing cobalt nitrogen carbon catalyst, comprising mixing carbon carrier dispersion with organic ligand solution for adsorbing organic ligand on surface of carbon carrier, adding cobalt metal salt solution to form metal ion as center, where the organic ligand adsorbed by carbon carrier is bridged periodic network structure porous material, calcining purified sample under protection of an inert gas to obtain cobalt nitrogen carbon catalyst. catalyst, comprising cobalt-nitrogen-carbon catalyst.
