(Invited) Dynamic Electrochemical Interface for Oxygen Evolution Reaction

Abstract

The performance of electrochemical energy conversion reaction is determined by the charge and mass transfer at electrochemical interface since the electrochemical reaction occurs at the electrochemical interface between the electrode and the electrolyte. However, the understanding of the electrochemical interface is often overlooked, and most studies focus on the electrode (or the electrolyte) itself as a separate approach, hindering its application to electrochemical energy devices. Here, I will discuss the dynamic behavior in electrochemical interface in water electrolysis. Unlike the conventional ‘frozen’ interface, the properties of the dynamic interface are determined by the continuous chemical and electrochemical interaction between electrolyte and electrode, and based on this, it opens the possibility of new system that can overcome existing thermodynamic limitation and can accomplish ‘dynamic stability’, new types of stability in electrochemical interface level.
