“…However, it was concluded that plant extracts as corrosion inhibitors get slightly degraded with temperature and time, which reduce the plant extract inhibitor efficacy for mild steel at temperatures above room temperature. [8][9][10][11][12][13][14][15][16][17][18] As a result of these limitations, scientists have made an effort to decorate or modify plant extracts to enhance their efficacy when used as corrosion inhibitors above room temperature.…”

This study combines experimental and theoretical explorations. The corrosion inhibition performance of different concentrations (50, 100, 250, and 500 ppm) of folic acid in 3.5 wt% NaCl solution on Q235 steel was tested by weight loss and electrochemical test. The corrosion inhibition efficiency increased with the gradual increase of folic acid concentration and reached a maximum of 87% at 500 ppm folic acid. The experimental results for electrochemistry and weight loss are in good agreement with the simulation calculations. The adsorption of folic acid on the steel surface obeyed the Langmuir isotherm, and the adsorption process was a combination of chemisorption and physisorption. The contact angle test also yielded the maximum increase in hydrophobicity of the specimen surface at the added folic acid concentration of 500 ppm. The corrosion morphology after the addition of corrosion inhibitor was relatively flat. The adsorption orientation of folic acid molecules on the steel surface in an aqueous environment was investigated using density functional theory (DFT)/molecular dynamics (MD) simulations. The microscopic mechanism of action of folic acid corrosion inhibitors is clarified.

This study investigates the green corrosion inhibition of mild steel in 1.0 M HCl using Myrtus communis essential oil (EOMC). Experimental and computational methods were combined to evaluate the corrosion inhibition effectiveness of EOMC. Weight loss measurements and electrochemical techniques, demonstrated that EOMC achieves a maximum corrosion inhibition efficiency of 94.81% at a concentration of 400 ppm of MCEO extract. The icorr significantly decreased from 983 µA/cm2 in the 1.0 M HCl solution to 51 µA/cm2 at 10−3 M, demonstrating the inhibitor's effectiveness. Polarization studies suggested mixed‐type inhibition, affecting both anodic and cathodic reactions, supported by changes in Tafel slopes. The Rct reached 462 Ω cm2 at 400 ppm of EOMC, enhancing the steel's protective capability. Higher temperatures increased the corrosion rate, with icorr values rising from 51 µA/cm2 at 298 K to 501 µA/cm2. Surface analysis using scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy (SEM‐EDX) confirmed the formation of a protective layer on the steel surface in the presence of EOMC. Additionally, density functional theory (DFT) calculations and molecular dynamics (MD) simulations provided further insights into the adsorption behavior of the EOMC molecules on the MS surface, revealing that the inhibition process involves both physisorption and chemisorption mechanisms.
