A Review of Study Progress of Pt Core-shell Structure ORR Catalysts
This paper describes the slow kinetics and high activation potential barrier of cathodic oxygen reduction reactions in energy conversion technologies such as fuel cells and metal air batteries.The new core-shell structure catalyst with metal Pt as the shell has the advantages of high catalytic activity and strong stability in the electrolyte.It explores the research progress of Pt based core-shell catalysts in the field of ORR catalysis,introduces the selection of various core materials,summarizes typical synthesis methods,and discusses their broad application prospects.
