Abstract

The invention relates to a carbon supported non-noble metal oxygen reduction compound catalyst, and a preparation method and application thereof. The carbon supported non-noble metal oxygen reduction compound catalyst includes a carbon carrier, pyrrole monomer, an oxidant and a non-noble metal salt. The mass ratio of a carbon material to pyrrole monomer is 0.01:0.99-0.99:0.01; the weight of the oxidant is 0.01-15 times that of the pyrrole monomer; and the non-noble metal salt accounts for 1-40 wt% in the catalyst. The preparation method of the catalyst provided by the invention has the advantages of simpleness, easy operation and low cost, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a carbon-supported non-noble metal oxygen reduction composite catalyst, and relates to its preparation method and application. Background technique [0002] Fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through electrochemical reaction without combustion. With continuous breakthroughs in research and development technology, it is expected to be widely used in electric vehicles, power stations, backup power supplies, and portable appliances. However, the key materials of fuel cells, especially the cathode and anode catalysts, limit the wide application of fuel cells. This is because the current effective catalysts for electrodes are mainly noble metal catalysts based on platinum group metals, which are not only scarce in resources, but also expensive. It cannot catalyze oxygen reduction with a complete 4-electron pathway, and has low selectivity for ...
