| Popis: | In this article, we evaluated the inhibitory performance of imidazo[4,5-b] pyridine derivatives namely, 6-bromo-2-(4-chlorophenyl)-3-(prop-2-yn-1-yl)-3H-imidazo[4,5-b]pyridine(SB9a) and 6-bromo-2-(4-chlorophenyl)-3-decyl-3H-imidazo[4,5-b]pyridine (SB14a) against mild steel (MS) corrosion in 1 M HCl using weight Loss from 303 to 333 K, Potentiodynamic Polarization (PDP), Electrochemical Impedance Spectroscopy (EIS), Scanning Electron Microscopy (SEM), energy dispersive X-ray (EDX) analysis, UV–vis spectroscopy and computational approach. The studied inhibitors showed a high inhibition performance since achieving a percentage of 90 % for SB14a and 88 % for SB9a 0.1 mM. PDP indicates that the both derivatives behaved as mixed-type inhibitors. Density functional theory (DFT) and molecular dynamic simulation (MD)) supports the experimental results. |
