摘要	The integration of atom clusters and single atoms into a unified system represents a desirable approach for attaining enhanced catalytic performance. Nonetheless, the controllable synthesis of a single-atom and nanocluster integrated system (SA-NC) faces considerable challenges, and the mechanisms underlying the catalytic activity remain poorly understood. In this research, a cobalt-based catalyst containing both coordinatively unsaturated single-atom (CoN3) and small nanoclusters (Co@SA-NC) is synthesized. The Co@SA-NC not only facilitates charge and mass transfer due to the interconnected long-range micromorphology, thus endowing efficient oxygen electrocatalytic reaction (ORR/OER), but also undergoes surface reconfiguration upon OH adsorption at high potentials in alkaline ORR/OER conditions. More appealingly, this OH-involved reconfigured adaptive structure promotes optimization of energy barriers owing to the dynamic regulation from the bridged OH between Co single-atom and cluster in the whole reaction process. Specific to the application metrics, a zinc-air battery assembled using the Co@SA-NC catalyst exhibit targeted power density enhancement with 270 mW cm-2 in an alkaline medium. This work offers an effective insight into the study of SA-NC catalytic reaction pathways for efficient ORR/OER catalysis. Owing to the surface reconfiguration upon OH adsorption, the atomic interactions between CoN3 single-atom and cluster promote the ORR/OER activity. Similar to the cooperation of basketball players, the bridging OH delivers the synergistic effect of Co@SA-NC via dynamic regulation in the whole reaction process, conducive to adjusting the rate-determining step and optimizing the energy barriers, realizing a self-adaptive catalysis. image
