    Advanced evaluation of novel quinoline derivatives for corrosion inhibition of mild steel in acidic environments: A comprehensive electrochemical, computational, and surface study
    (Elsevier, 2024) Belkheiri, Azzeddine; Dahmani, Khadija; Mzioud, Khaoula; Rbaa, Mohamed; Galai, Mouhsine; Hmada, Abdelfettah; Erdogan, Saban
    Corrosion poses a significant threat to the integrity and longevity of iron and its alloys, which are crucial materials for modern industry and infrastructure. This study investigates the effectiveness of two recently synthesized inhibitors based on quinoline structures: MPQ (2-methyl-5-(propoxymethyl) quinolin-8-ol) and AAQ ((((2aminoethyl)amino)methyl)-2-methylquinolin-8-ol) in protecting steel against environmental degradation, particularly in acidic and chloride-rich conditions such as hydrochloric acid. The inhibitors exhibited significant corrosion inhibition efficiencies of 92.37 % for MPQ and 84.13 % for AAQ, as demonstrated through electrochemical analysis. Surface characterization techniques, including SEM-EDX(Scanning Electron Microscopy with Energy Dispersive X-ray analysis), AFM (Atomic Force Microscopy), and contact angle measurements, revealed the formation of a protective barrier film that reduces the corrosion rate. Additionally, theoretical calculations using the Gaussian package provided insights into the adsorption behaviors and protective mechanisms of the inhibitors on mild steel surfaces. The findings contribute to the ongoing search for viable corrosion inhibitors, offering prospects for application in industries and critical infrastructures to enhance corrosion protection and durability.

    (Elsevier, 2022) Berdimurodov, Elyor; Kholikov, Abduvali; Akbarov, Khamdam; Guo, Lei; Umirov, Nurbek; Verma, Dakeshwar Kumar; Rbaa, Mohamed
    The corrosion of metal materials is an ongoing problem in the chemical industry. The use of sustainable and green technologies in corrosion protection is a very important task, because, the rise in environmental and ecological awareness. Currently, ionic liquids (ILs) based corrosion inhibitors are widely performed to protect the metal materials from the aggressive corrosion environment in the chemical industry. This is due to the ionic liquids are environmental-friendly, more sustainable, and have excellent corrosion-resistance organic molecules at low concentrations. In addition, the ILs are good soluble, non-toxic behaviour, non-inflammability, low volatility, good adsorbent, high thermal, and chemical stable in the aggressive medium. Besides, ILs have large planer anionic and cationic groups, which support an intermolecular synergism behavior; as a result, the adsorption of ILs is increased. These properties make ILs be a more efficient inhibitor. The ILs effectively protect the metal materials included steel, copper, magnesium, zinc and aluminum in the acid cleaning, descaling, pickling, gas or oil processes and desalination applications. In this chapter, the types, inhibition mechanism, inhibition properties of ILs, theoretical and experimental insights in the ILs inhibition mechanism were reviewed. © 2022 Elsevier Inc.

    New and Green Corrosion Inhibitor Based on New Imidazole Derivate for Carbon Steel in 1 M HCl Medium: Experimental and Theoretical Analyses
    (Trans Tech Publications Ltd, 2022) Berdimurodov, Elyor; Kholikov, Abduvali; Akbarov, Khamdam; Guo, Lei; Kaya, Savas; Verma, Dakeshwar Kumar; Rbaa, Mohamed
    In this research work, a new and green corrosion inhibitor based on new imidazole derivate (IMD) was introduced for carbon steel in 1 M HCl medium. Its inhibition properties were fully characterised by the gravimetric, electrochemical, surface and quantum chemical analyses. The experimental results confirmed that the inhibition efficiency of IMD was over 99% at 150 mg/L, forming a protective hydrophobic film on the metal surface, which maximally blocked the cathodic and anodic corrosive processes by adsorption. The electrochemical results suggested that the IMD is a mixed-type inhibitor. The adsorption behaviour of IMD was obeyed by Langmuir isotherms. The gravimetric results show that the inhibition efficiency depends on the change of concentration and temperature. The experimental tests were supported by the DFT (density functional theory) measurements, and a good relationship was found among these tests. The observed results of the surface analysis indicated that the metal surface was seriously improved with the presence of IMD.

    (Elsevier, 2022) Berdimurodov, Elyor; Kholikov, Abduvali; Akbarov, Khamdam; Guo, Lei; Katin, Konstantin P.; Verma, Dakeshwar Kumar; Rbaa, Mohamed
    The corrosion of steel materials in alkaline-saline media is the largest problem in industry. Economical and environmentally friendly corrosion inhibitors are crucial for corrosion protection. The present work is the first to introduce a novel cucurbit[6]uril-based [3]rotaxane supramolecular ionic liquid (CB6-based [3]rotaxane) as a green and efficient corrosion inhibitor for the chemical industry. The correlation between the supramolecular ionic liquid system and inhibition behavior was studied first. The inhibition characteristics of CB6-based [3] rotaxane in 1 M OH- + 1 M Cl- solution were first fully investigated by thermodynamic, gravimetric, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), electrochemical noise (EN), cyclic voltammetry (CV), density functional theory (DFT), molecular dynamics (MD) simulation, scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDX) methods. The experimental results confirmed that CB6-based [3]rotaxane exhibited excellent corrosion resistance, and its inhibition efficiency was 97.97% at 100 mg/L and 0.032 mM. The electrochemical results suggested that (i) CB6-based [3]rotaxane was a mixed-type corrosion inhibitor with anodic dominance; (ii) the supramolecular part of selected ionic liquid is responsible for notably blocks the charge transfer process on the metal surface. The theoretical findings correlated well with the experimental results and revealed that the protonated form of this supramolecular structure exhibited better performance than its neutral form. MD simulations results suggested that the bond length of the Fe(surface)inhibitor (3.127 angstrom) is less than 3.5 angstrom, which indicates that chemisorption is dominant in the investigated adsorption system. Molecular electrostatic potential analysis confirmed that the studied ionic liquidsupramolecular system contained most favorable nucleophilic centers, which are responsible for excellent inhibition performance.

    (Elsevier Science Sa, 2022) Berdimurodov, Elyor; Kholikov, Abduvali; Akbarov, Khamdam; Guo, Lei; Kaya, Savas; Verma, Dakeshwar Kumar; Rbaa, Mohamed
    Background: The corrosion of St3 steel in 1 M NaCl saturated with CO2 and H2S is a large problem in the chemical industry; therefore, creating green and more efficient inhibitors is an urgent task. However, there have been extremely limited research results related to this problem. In this research, a novel glycoluril pharmaceutically active compound (GCU) was first introduced as a green corrosion inhibitor for St3 steel in 1 M NaCl saturated with CO2 and H2S. Methods: The inhibition properties of the novel glycoluril pharmaceutically active compound were fully characterized by thermodynamic, gravimetric, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), electrochemical frequency modulation (EFM), linear polarization resistance (LPR), density functional theory (DFT), molecular dynamics (MD) simulation, scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDX) methods. Significant findings: The obtained results indicated that this inhibitor is an excellent inhibitory molecule, and its maximum protection degree was 95.62% at 100 mg/L/0.08 mM. The adsorption behaviour of this inhibitor was characterized from a Langmuir isotherm. Electrochemical studies demonstrated that this molecule is a mixed-type corrosion inhibitor. The theoretical calculations indicated a good correlation with the experimental results and confirmed that the adsorption-inhibition character depends on the molecular structure of the inhibitor and that the protonated form of the inhibitor is more inhibited than its neutral form.
