“…This is related to the adsorption of p -TSAH or p -TSAE via the organic hetero atoms (S, N and O) and the aromatic moieties, blocking the corrosion active sites and slowing down the current flow. 44 The values of the corrosion current are 2791 μA cm −2 for the blank 1 M HCl solution, 1453 μA cm −2 for the p -TSAE compound and 1287 μA cm −2 for the p -TSAH compound at the lowest concentration of 1.00 × 10 −5 M, so the corrosion of steel is decreased by the addition of p -TSAH or p -TSAE molecules. The successive addition of the inhibitor molecules gradually decreases the current density.…”

“…If ∆N > 0, electrons can be transferred from organic molecules to metals and form feedback (back-donation) bonds. If ∆N < 3.6, the inhibition efficiency increases with increasing ability to donate electrons to the metal surface [61,72]. Per Table 5, the ∆N values of all the compounds are in the range from 0 to 3.6, revealing that they can interact with the metal via electron donation from the inhibitor to the metal surface.…”

“…Molecular dynamics simulation is a comprehensive technology that combines mathematics, chemistry and physics through computational simulations to calculate the properties of materials in the system [61,[71][72][73]. In order to better understand the interaction between ECSL and the carbon steel surface, and furthermore, to elucidate its corrosion inhibition mechanism, MDS was performed to analyze the adsorption behaviors of the active components of ECSL on the Fe(110) surface at the molecular level.…”

Cucumber (Cucumis sativus L.) Leaf Extract as a Green Corrosion Inhibitor for Carbon Steel in Acidic Solution: Electrochemical, Functional and Molecular Analysis

An extract of cucumber leaves (ECSL) was prepared as a green corrosion inhibitor for carbon steel. Its carbon steel corrosion inhibition performance against 0.5 mol L−1 H2SO4 was investigated using electrochemical methods and scanning electron microscopy (SEM). Its composition was analyzed by gas chromatography and mass spectroscopy (GC−MS). Quantum chemical calculations and molecular dynamics simulations (MDS) were conducted to elucidate the adsorption mechanism of the inhibitor molecules on the carbon steel surface. The results indicated that the inhibition efficiency increases with its increasing concentration. The extract acted as a mixed type corrosion inhibitor, and its inhibition properties were ascribed to the geometric coverage effect induced by its adsorption on the metal surface in accordance with Langmuir’s law. The active components in the extract were identified as mainly organic compounds with functional groups such as aromatic moieties and heteroatoms. The inhibition activities of ECSL are delivered through the ability of the active components to adsorb on the metal surface through their functional groups to form a protective layer which hinders the contact of aggressive substances with carbon steel and thus suppresses its corrosion. This research provides an important reference for the design of green corrosion inhibitors based on plant waste materials.

“…In this setting, the utilization of ΔG ads determines spontaneous adsorption. It is used to predict their reaction feasibility [27], thus making this research practical in correlation with the nature of thermodynamics. All this allows us to assert that it is expedient to conduct a study on developing the natural plant as a green corrosion inhibitor.…”

The critical role of newly green corrosion inhibitors shows the disruption of cathodic and anodic reactions at the metals and solution interface. The object of this study is the development of Saga as a corrosion inhibitor to mitigate the effect of corrosive HCl 1M оn mild steel. The inhibitor was extracted using methanol to prepare various concentrations. Fourier transform infrared (FTIR) spectroscopy was used to determine the functional group of the inhibitor. The electrochemical impedance spectroscopy aided by the potentiodynamic polarization was utilized to evaluate the inhibitor’s effectiveness. Optical emission spectroscopy (OES) was implemented to determine the percentage of elements in mild steel. Based on the FTIR results, C=O, -OH, C=C, benzene, and C-O are accountable for the inhibitor to donate its lone pair of an electron to the 3-d orbital of iron metal. Increasing the inhibitor concentration decreases the capacitive double layer to elevate the inhibitor resistance. The higher inhibitor resistance of 29.33 Ω cm-1 increases as the concentration increases due to the depression of Cdl 420.16 µF cm2 at 10 ml inhibitor solution. Parallelly, it increases the inhibition efficiency at 65.58 %, slightly lower than the PP measurement of nearly 88 %. The higher value of adsorption/desorption constant, Kads, at 2.9 L mol-1 shows the strength of the inhibitor, which lowers the value of Gibbs free energy (ΔGads). The Saga inhibitor is considered a chemisorption inhibitor ΔGads –36.87 kJ/mol. The value demonstrates the formation of dative covalent bonding, which promotes the transferred electron from the inhibitor to the substrate. On the other hand, the Saga inhibitor abides by the Langmuir adsorption isotherm as the R2 value is 0.99.
