In situ PM-IRRAS of a glassy carbon electrode/deep eutectic solvent interface.
The interface of a 1 : 2 molar choline chloride/ethylene glycol deep eutectic solvent with a glassy carbon electrode has been investigated by polarization modulation reflection-absorption spectroscopy (PM-IRRAS). Temporal spectral changes at open circuit potential show the experiments to be surface sensitive and indicate slow adsorption of electrolyte molecules on the electrode surface. In situ...
متن کاملIn situ Raman spectroelectrochemistry of azobenzene monolayers on glassy carbon.
In situ Raman spectra of chemisorbed azobenzene (AB) monolayers on glassy carbon (GC) electrodes were observed under potentiostatic conditions in acetonitrile (ACN) with tetrabutyl-ammonium tetrafluoroborate (TBA-BF4). The Raman intensities of these spectra were high below -1000 mV, and this is attributed to the change in absorbance of AB on GC. In this paper, we describe chemisorbed AB molecul...
متن کاملSpecific interaction restrains structural transitions of an amphiphilic peptide in pulmonary surfactant model systems: an in situ PM-IRRAS investigation.
In situ polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) at the air-water interface has been used to determine secondary structure of the pulmonary surfactant model peptide, Hel 13-5, in the absence and the presence of phospholipid monolayers. Herein, fully saturated phospholipids of DPPC and DPPG are utilized to understand the effect of specific interaction betwee...

In order perform in situ measurements during heterogeneous reactions, such as water gas shift and methanol reforming on Pt(111) an existing Ultra High Vacuum (UHV) chamber has been rebuilt and expanded with a new High Pressure Cell (HPC), which allows us to perform Polarization Modulation Infrared Reflection Absorption Spectroscopy (PM-IRRAS) . This system has been used to examine the isotopic ...
متن کاملGlassy Carbon/KCl-Solution Interface Impedance. Mechanical Surface Treatment Effect
The dependence of complex impedance behaviour on mechanical surface treatment of glassy carbon electrodes in standard water KCl solutions at room temperature was investigated. A considerable frequency dependence of both the real and the imaginary term of the impedance was observed in the entire 1 5 0 kHz range of frequencies used for electrodes of different surface roughness. The results are di...
