A novel bimetallic RuFe nanocluster to enable highly efficient oxygen reduction in zinc-air batteries
文献摘要：
Zinc-air batteries(ZABs)have the advantages of high energy density and safety but their large-scale application is hindered by sluggish kinetics of four-electron aqueous O2 redox reactions.Widely used Ruthenium(Ru)-based catalysts possess intrinsic oxygen evolution catalytic activity but suffer from insufficient oxygen reduction reac-tion(ORR)performance.Herein,to optimize the ORR activity of Ru-based catalyst,an iron(Fe)-coordinated,bimetallic RuFe cluster is constructed and homogeneously dispersed within nitrogen(N)-doped carbon layers(denoted as RuFe@NC).Benefitting from the optimized ORR activity and more active site exposure,the RuFe@NC exhibits superior ORR activity with a half wave potential(E1/2)of 0.88 V higher than that of Pt/C(0.82 V).Accordingly,the RuFe@NC-based ZAB outperforms the Pt/C+IrO2-based device,presenting a reduced polari-zation of 0.7 V and an enhanced cycling lifetime of 50 h at 10 mA cm 2.Moreover,the optimized structural design ultralow Ru loading(0.013 mgRu cm-2)overcomes the cost barriers and demonstrates its high practicality.This bimetallic RuFe nanocluster opens a new way for future design of more efficient and stable catalytic systems.
