英文摘要This study investigated corrosion inhibition of task-specific ionic liquids, 1-(4-sulfonic acid) butyl-3-ethyl imidazolium hydrogen sulfate and 1-(4-sulfonic acid) butyl-3-decyl imidazolium hydrogen sulfate, for carbon steel in 0.5 M HCl by electrochemical tests, SEM, UV-vis, XPS, contact angle measurements, molecular orbital theory, and MD simulations. The inhibition efficiency of both ionic liquids increased with concentration, and the latter one shows higher inhibition efficiency of 97.9% due to the weaker hydrophilicity caused by increased alkyl tail. The mechanism of inhibition was found to be through adsorption onto the steel surface with cycling donation and back-donation of electrons.
