Abstract: The development of electrochemical energy technology is of great significance for solving the energy and environment problems. Investigating the processes of electrocatalytic reactions on the electrode surface at the atomic and molecular scale benefits reaction mecha-nisms studies, and provides the fundamental guideline for designing high-efficient and stable electrocatalysts. This review summarizes recent studies on investigating surface processes in electrocatalysis by scanning tunneling microscopy, including non-reactive processes such as surface adsorption, surface diffusion, reactants binding, and reaction processes such as structure changes and contrast transformations of catalysts, as well as distinguishing active sites. The key scientific issues and future developments in the field are also outlined.
