“…There are weak electrostatic interactions between the metal surface and the inhibitor, such as Van der Waals, in physical adsorption and the literature findings support that the ΔG o ads values are -20 kJ mol -1 or less. In chemical adsorption, on the contrary, there is a coordinated type of bond formation between the metal surface and the organic inhibitor molecule which supports charge transfer or sharing, and the literature findings support that the ΔG o ads values are -40 kJ mol -1 or higher [50,54,55]. In Table 4, the ΔG o ads values at all temperatures were even more negative than -40 kJ mol -1 .…”

This study covers the stages of testing whether the azo dye with chemical name (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc (II) chloride (DMT), known as Maxilon Red GRL in the dye industry, can be used as an anticorrosive feasible inhibitory agent, especially in industrial areas other than carpet, yarn and fibre dyeing. These test stages consist of the electrochemical measurement techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) for diverse concentrations and durations. The adsorption of the viewed DMT molecule on the mild steel surface obeyed the Langmuir isotherm. The zero charge potential (PZC) of mild steel was also found to assess the inhibition mechanism in containing DMT solution. The inhibition performance of DMT on the mild steel in a 1.0 M HCl solution was also investigated using methods such as metal microscope, atomic force microscope (AFM) and field emission scanning electron microscope (FE-SEM).

“…It can be seen from Table 1, in solutions containing different concentrations of lignin-EPTAC, the corrosion rate was dramatically reduced from 1.527 mg • cm 2 • hr −1 of 0 mg/L lignin-EPTAC to 0.033 mg • cm 2 • hr −1 of 100 mg/L lignin-EPTAC. The corrosion inhibition efficiency reached the highest value, 97.80%, at 100 mg/L.…”

“…Corrosion means that the material changes due to the action of the medium, transforming into a new state, leading to the destruction of material and functional failure. [1][2][3] Due to the widespread use of metallic materials, the problem of corrosion is almost in all walks of life, and the damage caused by corrosion is far greater than the sum of natural disasters and other types of accidents. [4][5][6][7][8] Today's anticorrosion measures mainly include corrosion-resistant materials, anode and cathode protection, surface coating, corrosion inhibitors, and so on.…”

Organic corrosion inhibitors from natural plant resources have received extensive attention in recent years. Herein, an eco-friendly corrosion inhibitor lignin-(2,3-epoxypropyl)trimethyl ammonium chloride (EPTAC) was successfully prepared by grafting EPTAC to kraft lignin. The inhibiting efficiency and its inhibition mechanism were investigated using electrochemical methods, adsorption thermodynamics analysis, and molecular dynamic simulation. The results showed that the lignin-EPTAC molecules formed a protective film on iron surface, resulting in an excellent inhibition efficiency of 97.80% at 100 mg/L concentration. The average surface roughness of steel samples was reduced to 26.6 nm from the original 99.3 nm. The adsorption of lignin-EPTAC molecules on the steel surface follows Langmuir adsorption isotherm model and was a physical-chemical process as well as an exothermic process of entropy reduction. This adsorption of lignin-EPTAC was a conjugated system dominated by benzene ring of lignin-EPTAC to form a chemical bond on the steel surface by conjugation, besides a positive interaction between the metal surface and the positively charged N ions in the head group of lignin-EPTAC.

Two carbon dots namely, S, N co-doped (CD1) and N doped (CD2) were synthesized by solvothermal treatment of pyromelletic acid in presence of thiourea, urea and DETA at 180°C. The synthesized carbon dots were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Transmission electron microscopy (TEM) and Raman spectroscopy analysis. The dimension of synthesized carbon dots were found in the range of 1.63 nm to 2 nm with significant graphitic carbons. These carbon dots (CD1 and CD2) were used as green corrosion inhibitor to mitigate corrosion of mild steel (MS) in 15 % HCl solution using gravimetric and electrochemical methods. Studied carbon dots, CD1 and CD2 exhibited inhibition efficiency of 96.40 and 90.00 %, respectively, at 100 ppm concentration and 303 K temperature. The observed corrosion inhibition occurs due to adsorption of the carbon dots to the MS surface. Both the carbon dots follow Langmuir adsorption isotherm model and show physisorption on the MS surface. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) analysis was used to study the morphology of the uninhibited and inhibited surface of the sample. The interaction of the carbon dots and composition of adsorbed layer on the MS surface was confirmed using X-ray photoelectron spectroscopy (XPS). The XPS analysis revealed that heteroatoms present in the structural moiety of the carbon dots efficiently binds on the MS surface.
