In-situ Microscope FTIR Reflection Spectroscopy and Its Applications in Electrochemical Adsorption and Electrocatalysis on Nanostructured Surfaces

Sixty years of electrochemical optical spectroscopy: a retrospective

“…Between the 1960s and 1970s, electrochemists seized the opportunity provided by the rapid development of spectroscopy at that time, and established a number of electrochemical optical spectroscopy technologies. 5 In 1963, the first in situ electrochemical optical spectroscopy, that is, electrochemical ellipsometry (ECellipsometry) experiments, was reported by Bockris et al 7 They kept the current constant while recording the changes in the intensity of the polarized light on the surface of the electrode This journal is © The Royal Society of Chemistry 2024 using an ellipsometer in real time (the method was referred to as ''chronoellipsometry'' in this work); the formation and growth mechanisms of the thin calomel film on the mercury electrode were in situ studied (see Fig. 1A for the electrochemical cell).…”

“…45,50 Thanks to the pioneering work and the excellent surface detection sensitivity, electrochemical surface-enhanced spectroscopy has become a significant experimental subfield in spectroelectrochemistry. 5,45,61,101,102…”

In Situ Fourier Transform Infrared Spectroelectrochemistry for Ethanol Oxidation in Alkaline Media

“…FTIRS provides a molecular-level description for the character of adsorption of organic molecules at electrode surfaces, and for the identification of intermediate/products of the electrode reactions as a function of reaction time and electrode potential. 8 FTIRS has been favorably used for the mechanistic studies of EO in acidic media. During the past few years, the applications of FTIRS for EO in alkaline media have also emerged in literature.…”

Electrochemical Construction of Nanostructured Materials and Their Anomalous Infrared Properties

“…Among the different novel properties, the anomalous infrared properties of nanostructured materials, namely (surface) enhanced IR absorption ((S)EIRA), 1,2 abnormal IR effects (AIREs), 3,4 and Fanolike IR resonance 5,6 have attracted extensive attentions in recent years. 7,8 The anomalous IR properties of nanostructured materials involve in fact many essential aspects of multi-disciplines, and consist in an important subject of frontier studies. The study has extended, on the one hand, the knowledge concerning the anomalous optical phenomena, and has contributed in developing the fundamental of nanomaterials on the other.…”
