Abstract

An axially S-coordinated Co─Zn diatomic catalyst was successfully synthesized via a tailored molecular cage-confined coordination strategy. This unique structure triggered an electronic rearrangement at the CoN4 site, which reduced the antibonding orbital occupancy in the Co─OOH and facilitated *OOH adsorption. These synergistic effects collectively enhanced both the activity and stability of the oxygen reduction reaction (ORR).

具有轴向硫配位的Co-Zn双原子催化剂在高效氧还原反应中的破缺电荷对称性

采用分子笼限制配位策略，成功合成了一种轴向s配位Co─Zn双原子催化剂。这种独特的结构引发了CoN4位点的电子重排，减少了Co─OOH中的反键轨道占用，促进了*OOH的吸附。这些协同效应共同增强了氧还原反应（ORR）的活性和稳定性。
