Research on Catalysts for Oxygen Electrode Based on 3d Transition Metal

The electrocatalyst for oxygen reduction reaction(ORR) and the slow cathodic oxygen reduction reaction are the key bottleneck for the commercialization of low temperature fuel cell.In recent years,non-precious metal catalysts for oxygen reduction have gained particular interest in the research on low temperature fuel cells.In this paper,research progress on 3d transition metal-based electrocatalysts,including transition-metal macrocyclic compound,transition metal-nitrogen/carbon compound and transitional-metal chalcogenide and transitional-metal oxide for the oxygen electrode have been systematically reviewed in addition to a brief introduction of the reaction mechanism of ORR at cathode electrode and FCs.Research findings on how to improve the activity and durability of the catalysts,reduce costs of preparing catalysts,and to develop novel non-precious metal catalystsare were summarized.Problems were to be solved and the future of electrocatalyst were pointed out as well.
