The electrochemical corrosion properties of a set of multiwalled carbon nanotubes (MWCNT) with different average diameters (〈d〉 = 7–22 nm) and conventional carbon black Vulcan XC-72 were studied potentiostatically in 2 M H2SO4 at 80 °C. Effects of grinding and high-temperature treatment (2800 °C) in inert gas on the corrosion stability of MWCNT were also examined. Excitation of MWCNTs with large 〈d〉 in activator mill results in local disruption of the fine structure of the NTs and increase of the corrosion current densities. No rupture and changes of the corrosion behaviour occur for MWCNTs with lower 〈d〉 after grinding. High-temperature treatment of MWCNTs leads to removal of amorphous carbon and defects from the surface of the materials and results in drastic decrease of the reactivity of the surface of the materials towards electrocorrosion. The ABET-weighted corrosion current densities of the MWCNTs are significantly lower than that of conventional XC-72 material evidencing of their higher stability towards electrocorrosion.
