摘要：Currently,feni nanoalloys have received considerable attention for the oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)in rechargeable aqueous zinc(Zn)-air batteries(ZABs)because of their high content and good chemical ***,their poor electronic conductivity,small surface area,and sluggish activity seriously hinder their catalytic ***,S-modulated feni nanoalloys supported by hierarchically porous carbon(Sfeni/PC)are synthesized through the thermal treatment of metal-organic precursors for efficient bifunctional oxygen catalysis.S decoration endows S-feni/PC with a superior OER performance while maintaining an ORR performance that is comparable to that of Pt/***,S-feni/PC exhibits excellent bifunctional oxygen catalytic activity,outperforming the noble-metal-based composite catalysts of Pt/C and RuO_(2).Notably,the ZABs assembled with S-feni/PC exhibit high specific capacity(792 mA h g^(-1)),high peak power density(123.5 mW cm^(-2)),and remarkable durability for 700 charge/discharge cycles at 10 mA cm^(-2),which surpasses the performance of commercially available Pt/C-RuOand other catalysts in previously reported *** study will provide not only new bifunctional oxygen electrodes for efficient ZAB devices but also new insights into the design of feni-based materials for a wide range of catalytic applications.
