“…Figure 5 shows the appropriate Bode impedance modules for C-steel electrodes immersed in molar HCl with and without various inhibitor doses at its OCP. The increase of absolute impedance at low frequencies in the Bode plot confirms the higher protection with the increasing inhibitor concentration 43 . The concentration of DS036 and DS038 inhibitors in 1.0 M HCl is increased, as indicated by an increase in absolute impedance.…”

“…Additionally, these diagrams are identical for all concentrations tested, showing that the corrosion mechanism is unchanged 42 . The frequency dispersion of interfacial impedance may also be to blame for the fact that these Nyquist graphs are not perfect semicircles 43 . Chemical inhomogeneity, surface coarseness, and the adsorption–desorption process of inhibitive molecules on C- steel surfaces all contribute to this phenomenon 44 .…”

Two organoselenium thiourea derivatives, 1-(4-(methylselanyl)phenyl)-3-phenylthiourea (DS036) and 1-(4-(benzylselanyl)phenyl)-3-phenylthiourea (DS038) were produced and categorized using FTIR and NMR (1H and 13C). The effectiveness of the above two compounds as C-steel corrosion inhibitors in molar HCl was evaluated using the potentiodynamic polarization (PD) and electrochemical impedance spectroscopy (EIS) techniques. PD findings indicate that DS036 and DS038 have mixed-type features. EIS results show that growing their dose not only changes the polarization resistance of C-steel from 18.53 to 363.64 and 463.15 Ω cm2 but also alters the double layer capacitance from 710.9 to 49.7 and 20.5 μF cm−2 in the occurrence of 1.0 mM of DS036 and DS038, respectively. At a 1.0 mM dose, the organoselenium thiourea derivatives displayed the highest inhibition efficiency of 96.65% and 98.54%. The inhibitory molecule adsorption proceeded along the Langmuir isotherm on the steel substrate. The adsorption-free energy of the adsorption process was also intended and indicated a combined chemical and physical adsorption on the C-steel interface. FE-SEM studies support the adsorption and protective abilities of the OSe-based molecule inhibitor systems. In Silico calculations (DFT and MC simulations) explored the attraction between the studied organoselenium thiourea derivatives and corrosive solution anions on a Fe (110) surface. The obtained results show that these compounds can make a suitable preventing surface and control the corrosion rate.

“…7 shows the linearity relation between 𝐶 𝜃 ⁄ and 𝐶, which with R 2 nearly equivalent to 1. It supports the M-CuO and S-CuO NPs ability to adsorb to the MS surface, demonstrating that the components are occupying the MS/electrolyte interface's active spots (Oubaaqa et al 2022). M-CuO and S-CuO NPs molecules are stated to be adsorbed on the surface in a single layer without interacting with other molecules (Kouache et al 2022).…”

Due to its simplicity and eco-friendly, the use of plants to create metal oxide nanoparticles has recently attracted a lot of attention. Consequently, the purpose of this study was to generate CuO NPs utilizing two different techniques, including a synthetic approach and an aqueous extract of Moringa oleifera leaves (M-CuO NPs) (S-CuO NPs). Nanoparticles produced were evaluated by SEM, EDX, TEM and XRD, to considering the creation of CuO NPs and to determine the morphological, elemental constitution and size the sample. The average size 14.95 and 35.73 nm for S-CuO and M-CuO NPs respectively, having potentials for application as inhibitor in corrosion of MS. The inhibition and adsorption properties of prepared M-CuO NPs and S-CuO NPs on MS in 1M HCl were investigated using the wt reduction assessment. The maximal IEof prepared M-CuO NPs and S-CuO NPs was 95.06% and 92.10%, respectively, at 1000 ppm. The IE % improves with greater concentration of the prepared M-CuO NPs and S-CuO NPs. According to the findings, M-CuO NPs are the most effective green potential inhibitor for MS in acidic conditions. It is demonstrated that the Langmuir isotherms are obeyed by the produced CuO NPs and MS substrate.

Investigating the Inhibitory Properties of Cupressus sempervirens Extract against Copper Corrosion in 0.5 M H₂SO₄: Combining Quantum (Density Functional Theory Calculation–Monte Carlo Simulation) and Electrochemical-Surface Studies

The study investigates the potential of Cupressus sempervirens (EO) as a sustainable and eco-friendly inhibitor of copper corrosion in a 0.5 M sulfuric acid medium. The electrochemical impedance spectroscopy analysis shows that the effectiveness of corrosion inhibition rises with increasing inhibitor concentrations, reaching 94% with the application of 2 g/L of EO, and potentiodynamic polarization (PDP) studies reveal that EO functions as a mixed-type corrosion inhibitor. In addition, the Langmuir adsorption isotherm is an effective descriptor of its adsorption. Scanning electron microscopy/ energy-dispersive X-ray spectroscopy, atomic force microscopy surface examination, and contact angle measurement indicate that EO may form a barrier layer on the metal surface. Density functional theory calculations, Monte Carlo simulation models, and the radial distribution function were also used to provide a more detailed understanding of the corrosion protection mechanism. Overall, the findings suggest that Cupressus sempervirens (EO) has the potential to serve as an effective and sustainable corrosion inhibitor for copper in a sulfuric acid medium, contributing to the development of green corrosion inhibitors for environmentally friendly industrial processes.
