Abstract The development of bimetal based catalysts via interfacial engineered strategy has been intensively explored due to its great potential for enhancing the electrochemical performance. The significant progress achieved by the interfacial engineering is mainly derived from its great ability on tuning the intermediate adsorption, controlling the electron and mass transportation, preventing catalysts from serious aggregation, as well as providing advanced promoter for the rational design of highly efficient catalysts. Here, the recent works on the interfacial engineered strategy for developing highly efficient bimetal based electrocatalysts are outlined. The advantages of interfacial engineered strategy on manipulating the activity, selectivity, and stability of catalysts are first discussed. The recent synthetic approaches for controlling the interface structures and the related hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and electroreduction of carbon dioxide are elaborated based on three major categories, involving metal/metal, metal/metal compound, and metal/support interfaces. Challenges and perspectives of this field are represented in the final section.
