Description

The formation of surface films on carbon steel electrodes in aqueous methyldiethanolamine solutions, saturated with carbon dioxide at 80 °C was investigated using electrochemical impedance spectroscopy. The raw experimental and simulated electrochemical impedance data used to produce Figures 6, 7 and 11 are included.

Steps to reproduce

The data provided is unprocessed. Impedance data were recorded using a BioLogic potentiostat and EC-Lab software. The simulated impedance data were produced using EC-Lab software. A AgCl | Ag (saturated KCl) reference electrode was used. Therefore, the working electrode potential is vs. AgCl | Ag (saturated KCl). A full description of the reagents, solution temperature, composition and concentration can be found in the methods section of the manuscript.
