| چکیده مقاله |
| Electrocatalysts play key roles in the electrochemical energy conversion systems and because of the high price and limited resources of platinum, the development of platinum group metal (PGM)-free catalysts for oxygen reduction reaction (ORR) is critical for affordable polymer electrolyte membrane fuel cells (PEMFCs). But it’s still a big challenge to develop highly active, durable, and low-priced nonprecious metal electrocatalysts (NPMCs) to replace the Pt-based catalysts for ORR. In the last decade, due to some unique properties of metal-organic frameworks (MOFs), substantial progress has been made to develop highly active nonprecious metal electrocatalysts, from MOFs as precursors. Some NPMCs now exhibit ORR activities approaching that of PGM electrocatalysts in rotating disk electrode (RDE) measurements and only a few of them transformed into acceptable membrane electrode assembly (MEA) performance. In this review since the RDE level performance cannot be translated into the MEA level, the experiments at the MEA level are emphasized and from a practical viewpoint, NPMCs for ORR and the advantages and limitations in PEMFC are briefly reviewed and finally, challenges and prospects are discussed. |
