Electrochemical Quartz Crystal Microbalance (EQCM) is a testing technique that combines quartz crystal microbalance (QCM) and electrochemical detection. EQCM is one of effective methods to study the surface reaction due to its simplicity, rapidness, and the ability to dynamically detect the deposition, adsorption, or dissolution of an active material on a quartz crystal at nanogram level. At the same time, because the EQCM testing technology is an in-situ testing method, online real-time monitoring can be realized. With its high precision and high sensitivity, it is possible to further analyze the reaction process and deep-level mechanism at the surface interface. This paper summarizes the application of EQCM in the fields of electrochemical, biomedical and oil field chemistry, as well as research mechanism and dynamics, and puts forward the new research direction of EQCM and the problems in its development.
