氧还原反应（ORR）和析氧反应（OER）是可再生能源转换和储存装置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以提高能量转换效率。因此，人们一直致力于开发具有高活性和稳定性以及低成本的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的研究兴趣，因为它们的催化性能可以通过界面工程来调节。本文综述了金属/金属氧化物异质结构界面工程在ORR和OER方面的最新研究成果。首先讨论了金属/金属氧化物界面对催化的影响。然后，界面工程的方法进行了说明。介绍了界面工程在OER和ORR催化以及双功能电催化方面的研究进展。最后，展望了金属/金属氧化物界面工程在OER和ORR中的未来发展。
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.
