Imidazolium-derived ionic liquid as a steel corrosion inhibitor in acidic media: a synergistic study of experiments and DFT calculations
Wael. H. Alsaedi, Thaar M. D. Alharbi, M. Alahmadi, Ibrahim K. Alsulami, Mahmoud A. Bedair, Sami Ben Aoun3-Benzyl-1-propyl-imidazolium bromide (RD) inhibits carbon steel corrosion in 1 M HCl by spontaneous adsorption, forming a protective film. RD achieves 93.3% inhibition through mixed-type protection, supported by electrochemistry, surface analysis, DFT, and Monte Carlo simulations.
