摘要：

We successfully prepared Fe and Co isolated single atoms on metal-organic framework derived nitrogen-doped carbon (FeCo-ISAs/CN) by an adsorption-calcination strategy. The obtained FeCo-ISAs/CN exhibited top-level catalytic reactivity for the alkaline oxygen reduction reaction (ORR) with a half-wave potential of 0.920 V, which was 70 mV more positive than that of commercial Pt/C. Moreover, the catalyst was durable and showed negligible activity decay in the alkaline ORR during 5000 voltage cycles.
