The effectiveness of onion peel extract, (OPE), for carbon steel in one molar (1 M) hydrochloric acid solution was illustrated utilizing weight loss (WL) techniques, potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), and surface morphological examination. Also, this process was characterized using Fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), atomic force microscopy (AFM), and scanning electron microscope (SEM). The protective efficiency rises as OPE concentration rises and decreases with corrosive solution temperature, according to weight loss measurements. Polarization curves display that OPE behaves as a mixed-type inhibitor in hydrochloric acid. The adsorption process mechanism is supported by EIS, which demonstrates that charge-transfer resistance rises, and double-layer capacitance falls with inhibitor concentration. OPE adhering to carbon steel follows the Langmuir isotherm, through a physical adsorption process and the inhibitor molecules were shown to have spontaneously adsorbed onto the carbon steel based on the negative values of Gibb's free energy of adsorption. The synergistic effect of copper oxide nanoparticles, CuO-NPs in combination with OPE on the inhibition corrosion of carbon steel was evaluated. The results showed that the inhibition efficiency of OPE increases in the presence of CuO-NPs due to synergistic interactions of OPE extract molecules with CuO-NPs. The electron-donating capacity of the chemical component of the OPE has been shown in theoretical studies employing quantum chemistry methods.

“…By increasing the AHS concentrations, the corrosion rate was suppressed, and the inhibition performance was enhanced. This increase could be ascribed to the AHS molecules adsorbed on the surface active site [35]. The corrosion rates of the uninhibited samples are much higher than the inhibited sample, as shown in figure 3.…”

Traditional corrosion inhibitors have been frequently used for metal protection against strong acids. However, most of them are hazardous compounds with high costs. Therefore, due to the strict environmentally friendly regulations, green and low-cost compounds from renewable sources have gained high consideration in recent applications. In the present study, the Arachis hypogaea shell extract, commonly called groundnut, a cost-effective was selected to inhibit API X 65 pipeline steel corrosion in 1 mol·L−1 H2SO4 solution. The Arachis hypogaea shell composition was examined by FTIR analysis. The Arachis hypogaea shell on pipeline steel in H2SO4 solutions was studied via gravimetric, potentiodynamic polarization, and surface analysis (SEM and EDX). Electron donor atoms present in the Arachis hypogaea shell extract molecules is responsible for its adsorption on the surface of the metal. Experimental study shows that with increasing Arachis hypogaea shell concentrations, the inhibition tendency increased and reached 98.84% at 4g/L after 24 h. Arachis hypogaea shell extract behaved as mixed-type inhibitor, and the surface coverage fits the Langmuir isotherm, signifying that the steel surface was covered by a monolayer of inhibitor molecules without intermolecular interactions. SEM analysis shows that Arachis hypogaea molecule adsorption on the metal surface reduced considerably its dissolution rate resulting in a smooth and clean surface with few damaged areas. The use of water for extraction of Arachis hypogaea shell exhibiting inhibition efficiency, non-toxic, and cost-effective than other green inhibitors, proposes the Arachis hypogaea shell as an excellent green inhibitor for API X 65 steel corrosion in 1 mol·L−1 H2SO4 solution.

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.
