英文摘要	Precise synthesis of single-atom catalysts (SACs) with a homogeneous coordination environment and high metal loading remains a great challenge. Here, for the first time, we demonstrate the preparation of cobalt single atoms with an ultra-high metal loading of 20.5 wt% based on the two-dimensional conjugated organic framework of C2N. The porous framework of C2N provides confined space for trapping metal atoms and inhibiting metal aggregation, while the skeleton provides pairs of pyridinic nitrogens as coordination sites to immobilize metal atoms. The as-prepared catalyst exhibited bifunctional activity toward the oxygen reduction and oxygen evolution reactions (ORR and OER). The corresponding rechargeable zinc-air flow battery shows remarkable stability with no degradation even after continuous operation for 6000 cycles (equivalent to 1000 h), placing it as one of the most long-lasting zinc-air batteries. This confined synthetic strategy can be generalized to construct SACs of other metals with different element combinations.
