Abstract:

For a long time,carbon supported highly dispersed platinum catalysts and their alloys have been the most effective catalysts for oxygen reduction and hydrogen oxidation in commercial proton exchange membrane fuel cells(PEMFCs).Howe-ber,due to a series of problems,such as high cost,poor stability under electrochemical conditions,CO poisoning and slow kinetics of oxygen reduction reaction(ORR),the Pt-based catalyst has been hindered in its further application and large-scale production in fuel cells.In contrast,nitrogen-doped carbon nanomaterials have the characteristics of low cost,high activity,high stability and environmental friendliness,which make them have broad application prospects in the field of fuel cells.In this paper,based on the research status at home and abroad in recent years,the preparation methods of nitrogen-doped carbon nanomaterials,such as in-situ doping method,post doping synthesis method and direct pyrolysis method were reviewed,and their advantages and disadvantages were analyzed,as well as their research progress of ORR catalysts.Finally,the main development direction of nitrogen-doped carbon nanomaterials catalysts in the future was prospected.

Key words: nitrogen-doped carbon nanomaterials, oxygen reduction reaction, fuel cells
