Carbon and graphene-based quantum dots have recently emerged as highly valuable and widely applicable materials based on their low particle sizes (1−10 nm). The incorporated oxygen, nitrogen, and carbon functional groups can significantly enhance the binding capabilities of these materials to various surfaces. In this study, lupine seeds were employed to produce a sustainable and novel material known as lupine carbon quantum dots (LCQDs), by using a straightforward and green microwave hydrothermal reaction. The assembled LCQD material was characterized by several instrumentations such as FTIR, TEM, EDX, XRD, UV−vis, and XPS to confirm the various incorporated functionalities, morphology/particle size, elemental composition, amorphous structure, transition types, and various bonds, respectively. LCQD material was explored to investigate and assess the corrosion prevention performance by various approaches via electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and mass loss techniques. The prepared LCQDs reflected an 89.3% maximum inhibitory effectiveness for carbon steel corrosion upon using 175 mg/L LCQDs in a 1.0 M HCl environment at 40 °C. The EDX, XRD, and XPS techniques were used to confirm the effectiveness of LCQDs in protection of the carbon steel surface and discuss the corrosion inhibition mechanism. The LCQD adsorption mechanism onto carbon steel was also explored by Langmuir and Flory−Huggins isotherms, besides the kinetic−thermodynamic model, to fit the outcomes from the experimental data. The findings revealed that these models were applicable, giving ΔG o ads of −31 kJ/mol, while the adsorption mechanism was correlated to a physical/chemical process. Finally, the outcomes of this study refer to the potential capability of LCQD materials as sustainable corrosion inhibitors without any additional modification via doping or modification with other chemical compounds or materials.

“…In the oil industry, the acidization of petroleum oil wells, an important stimulation technique, is used to enhance production [35]. HCl, HClO 4 and H 2 SO 4 are the most applied acidic solutions because of their highly corrosive nature with regard to many metals and alloys even at low concentrations [36], whereas HNO 3 and H 3 PO 4 are used occasionally. In this study, the inhibition efficiencies of polyvinylpyrrolidone are mainly applied in different acid media such as perchloric acid, The inhibitor molecules strongly interact with the metal surface in the presence of perchlorate ions due to the low coordination capacity of perchlorate ions.…”

Polymers are materials composed of macromolecules characterized by duplicates of smaller molecules that are covalently bonded together to provide a set of properties. Corrosion inhibition by such compounds is usually attributed to their adsorption on the metal-solution interface. The inhibition effect of different sizes of polyvinylpyrrolidone (PVP) on the corrosion of carbon steel (C-steel) in solutions of perchloric acid was investigated. The inhibition efficiency increases as the size of the inhibitor and its concentration increases, but decreases as the temperature increases and can reach a value of 81.53% and 5.0x10^-3 mol L^-1(PVP: 58,000 g mol^-1) at 30°C. The most remarkable inhibition efficiency was confirmed by the presence of the film formed on the metal surface by scanning electron microscopy. The kinetic and thermodynamic parameters for the corrosion of C-steel and adsorption of the inhibitor were determined and discussed. The combination of PVP with potassium iodide produced a strong synergistic effect on the inhibition of C-steel corrosion leading to a significant improvement in the inhibition efficiency. Quantum chemical parameters were studied using density functional theory to determine the possible relationship between the inhibitor and its electronic properties.
