Chapter 3B In situ spectroscopic studies of the electrochemistry
Abstract
Most electrocatalysts would undergo a structural reconstruction during the electrochemical reactions, which involves the electron transfer between two-phase interfaces (solid/liquid, liquid/liquid, solid/solid; in most cases, it is the electrode/ electrolyte interface). In situ spectroscopic studies on the electrode/electrolyte interface can facilitate the real-time examinations of the structure and composition, which help the researchers better understand the mechanism of electrocatalysis. In this perspective, the historical development and recent applications of in situ spectroscopic techniques in tracking the structural reconstruction of electrocatalysis are thoroughly summarized. In particular, the electrochemical in situ Raman spectroscopy, attenuated total reflection Fourier-transform infrared spectroscopy, scanning probing microscopy, and mass spectrometer will be introduced in detail. Based on each in situ technique’s unique capabilities and limitations, an “in situ spectroscopic map” is established for characterizing electrode/electrolyte interfaces in a dynamic scene, which offers guidelines for developing the next-generation efficient electrocatalysts.
