主 题:Microwave-assistant Zeolitic imidazolate framework-8 Fe single atoms Electrocatalysts Oxygen reduction reaction
摘 要:Fe-N-C endowed with inexpensiveness,high activity,and excellent anti-poisoning power have emerged as promising candidate catalysts for oxygen reduction reaction(ORR).Single-atom Fe-N-C electrocatalysts derived from Fe-doped ZIF-8 represent the top-level ORR ***,the current fabrication of Fe-doped ZIF-8 relies on heavy consumption of time,energy,cost and organic ***,we develop a rapid and solvent-free method to produce Fe-doped ZIF-8 under microwave irradiation,which can be easily amplified in combination with *** rational pyrolysis,Fe-N-C catalysts with atomic FeN4 sites well dispersed on the hierarchically porous carbon matrix are obtained,which exhibit exceptional ORR performance with a half-wave potential of 0.782 V(*** hydrogen electrode(RHE))and brilliant methanol *** assembled direct methanol fuel cells(DMFCs)endow a peak power density of 61 mW cm^(-2) and extraordinary stability,highlighting the application perspective of this strategy.
