“…Benzimidazole is a heterocyclic aromatic organic compound with a bicyclic structure consisting of the fusion of benzene and imidazole rings [10], and hydrogen atoms on the rings can be substituted by other groups or atoms. Some derivatives of benzimidazole have been demonstrated as excellent inhibitors [22][23][24][25][26][27] for copper and its alloys in acidic solution, and exhibit different inhibition performance with the difference in substituent groups and substituent positions on the imidazole ring [21,28,29]. Thus, benzimidazoles are N-and O-containing compounds and good electron donors; this will enhance their adsorption on the surface of the copper metal and increase binding capabilities.…”

The inhibitive performance of seven synthesized 2-(2-benzimidazolyl)-4 (phenylazo) phenol (BPP_1-7) derivatives was investigated experimentally on the corrosion of copper in 2.0 M HNO 3 acid using mass loss, thermometric and DC potentiodynamic polarization techniques. Quantum chemical calculations was investigated to correlate the electronic structure parameters of the investigated benzimidazole derivatives with their inhibition efficiencies (IE%) values. Global reactivity parameters such as E HOMO , E LUMO , the energy gap between E LUMO and E HOMO (DE), chemical hardness, softness, electronegativity, proton affinity, electrophilicity and nucleophilicity have been calculated and discussed. Molecular dynamics simulation was applied on the compounds, to optimize the equilibrium configurations of the molecules on the copper surface. The areas containing N atoms are most possible sites for bonding Cu (111) surface by donating electrons. Binding constant (K b), active sites (1/y), lateral interaction (f), equilibrium constant (K ads) and standard free energy of adsorption (DG°) values obtained from either kinetic model and/or Frumkin adsorption isotherm were compared and discussed. Thermodynamic functions and activation parameters such as: E a , DH*, DS* and DG* at temperatures 303, 313, 323 and 333 K were determined and explained. IE% values of the examined compounds on Cu (111) surface followed the order arrangement: BPP_1 [ BPP_2 [ BPP_3 [ BPP_4 > BPP_5 [ BPP_6 [ BPP_7. The theoretical data obtained as compatible with experimental results showed that the studied benzimidazole derivatives (BPP_1-7) are effective inhibitors for the corrosion of copper in nitric acid solution.

“…Thus, development of high-performance inhibitors for controlling copper corrosion in environments containing chloride medium and under wet-dry alternation becomes a technical challenge. Generally, organic compounds can be modified to improve the strength of their adsorption bonds to the protected metals, providing a promising alternative for corrosion inhibition [25][26][27][28].…”

“…From the XPS survey spectra (Figure d), the N1s signal is observed for TTC‐Cu surface (Figure d2). As is shown in the N1s spectra for TTC‐Cu surface (Figure e2), the N1s peak is decomposed into two components centered at 399.6 and 401.6 eV, matching with the peak of Cu‐N and =N + H − group in the assembled TTC molecule, respectively. The presence of Cu‐N can be verified by the Cu2p spectra for TTC‐Cu surface (Figure f2), the bonding energy at 933.2 eV corresponds to the [Cu(I)‐azole] compound.…”

The triazole inhibitor of 1‐(p‐tolylthio)‐1H‐1,2,3‐triazole‐4‐carboxylic acid (TTC) was synthesized via the Cu(I)‐catalyzed azide‐alkyne 1,3‐dipolar cycloaddition reaction. The self‐assembling method was performed to fabricate the self‐assembled film of TTC on the copper surface. The electrochemical measurement results indicate that the TTC film can efficiently protect the copper from corrosion in high concentrated industrial cooling water. The protection efficiency of TTC film for copper is 92.2%. Surface characterizations imply that the copper with TTC film after corrosion is covered with multiple protective layers. It probably contains Cu(I) and Cu(II) complexes mixed with nitrogenous compound, Cl− and SO42−. The result of quantum chemical calculation shows that the superior performance of TTC film is related to the adsorption of TTC molecules on copper surface horizontally. This kind of adsorption is mainly achieved via the adsorption centers of triazole ring and O atoms in TTC molecule.
