Abstract
Abstract Negatively charged 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF4) | Mo2C derived micro-mesoporous carbon (C) electrode interface has been studied using in situ synchrotron radiation initiated X-ray photoelectron spectroscopy (XPS) in order to estimate true potentials when slow electrochemical processes start at the C electrode used in the supercapacitors. A three-electrode system within the very wide working electrode (WE) potential region down to -1.90 V (vs. Ag/AgCl wire in EMImBF4) has been used for the polarization of the C {WE} during the in situ {XPS} measurements. Parallel to {XPS} measurements in high vacuum chamber, the cyclic voltammetry measurements in the three-electrode system were carried out in the Ar-filled glovebox in order to obtain electrochemical data down to -2.40 V (vs. Ag/AgCl wire in EMImBF4) for studied C electrode material. {WE} potential vs. {XPS} spectra relationship has been established and discussed here.
