Oxygen reduction reactions (ORR) and oxygen evolution reactions (OER) are two very important electrochemical processes for renewable energy conversion and storage devices. Electrocatalysts are needed to accelerate their sluggish kinetics to improve energy conversion efficiencies. Hence, extensive efforts have been devoted to the development of OER and ORR electrocatalysts with high activity and stability as well as low cost. Among these developed electrocatalysts, metal/metal oxide heterostructures attract a great deal of research interest because their catalytic performances can be tuned by interface engineering. In this Review, the latest achievements in interface engineering of metal/metal oxides heterostructures toward ORR and OER are described. The effects of the metal/metal oxide interface on catalysis are first discussed. Then, the approaches for interface engineering are illustrated. The developments of interface engineering in OER and ORR catalysis as well as bifunctional electrocatalysis are further introduced. Lastly, a perspective for future development of interface engineering in metal/metal oxide for OER and ORR is discussed.
氧还原反应（ORR）和析氧反应（OER）是可再生能源转换和存储设备中两个非常重要的电化学过程。需要电催化剂来加速其缓慢的动力学过程，以提高能量转换效率。因此，人们已经投入了大量精力来开发具有高活性、稳定性且低成本的OER和ORR电催化剂。在这些已开发的电催化剂中，金属/金属氧化物异质结构吸引了大量研究兴趣，因为其催化性能可通过界面工程进行调控。在本综述中，描述了金属/金属氧化物异质结构在ORR和OER界面工程方面的最新成果。首先讨论了金属/金属氧化物界面在催化方面的影响。然后，阐述了界面工程的方法。进一步介绍了OER和ORR催化以及双功能电催化中界面工程的进展。最后，讨论了金属/金属氧化物用于OER和ORR的界面工程未来发展的前景。
