Oxygen reduction and evolution reactions constitute the core process of many vital energy storage or conversion techniques. However, the kinetic sluggishness of the oxygen redox reactions and heavy reliance on noble-metal-based electrocatalysts strongly limit the energy efficiency of the related devices. Developing high-performance noble-metal-free bifunctional ORR and OER electrocatalysts has gained worldwide attention, where much important progress has been made during the last decade. This review systematically addresses the design principles to obtain high-performance noble-metal-free bifunctional oxygen electrocatalysts by emphasizing strategies of both intrinsic activity regulation and active site integration. A statistical analysis of the reported bifunctional electrocatalysts is further carried out to reveal the composition-performance relationship and guide further exploration of emerging candidates. Finally, perspectives for developing advanced bifunctional oxygen electrocatalysts and aqueous rechargeable metal-air batteries are proposed.
氧还原和析氧反应构成了许多重要的能量存储或转换技术的核心过程。然而，氧氧化还原反应的动力学迟缓以及对基于贵金属的电催化剂的严重依赖，极大地限制了相关器件的能量效率。开发高性能的无贵金属双功能氧还原反应（ORR）和析氧反应（OER）电催化剂已引起全球关注，在过去十年中取得了许多重要进展。本综述系统地阐述了通过强调本征活性调控和活性位点整合策略来获得高性能无贵金属双功能氧电催化剂的设计原则。进一步对已报道的双功能电催化剂进行统计分析，以揭示组成-性能关系，并指导对新型候选材料的进一步探索。最后，提出了开发先进双功能氧电催化剂和水系可充电金属空气电池的前景。
