A comprehensive experimental and theoretical perspective of novel triazole-based pyridine and quinoline derivatives for corrosion protection of carbon steel in sulfuric acid solution.

ABSTRACT: Herein, we synthesized two novel triazole compounds (KB1 and KB2). Their efficiency in inhibiting corrosion of carbon steel (CS) in 0.5 M H₂SO₄ was evaluated using open circuit potential (OCP) vs. time, potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS), surface characterization methods, and computational studies. Based on EIS, the corrosion protection capacities of KB1 and KB2 increased with increasing concentration, reaching 86.9% and 92.4% at 9 × 10^- 5 M at 298 K for KB1 and KB2, respectively, which are consistent with the findings obtained via PP. The PP curves imply that KB1 and KB2 act as mixed-type inhibitors. Meanwhile, their adsorption on the surface of CS obeyed the Langmuir isotherm. Using EIS and PP approaches, the e
