“…Faster inhibition at more positive potentials agrees well with the findings of Yao et al, 15 who reported that BTAH is adsorbed on the copper surface at negative potentials, while formation of the ͓Cu͑I͒-BTA͔ film takes place at more positive potentials. The results for OF-HC copper are similar to what we have found previously for DHP copper; 21 however, the potential has stronger influence on DHP copper than on OF-HC copper.…”

The formation of inhibitive benzotriazole films on copper and copper alloyed with silver has been studied with scanning electrochemical microscopy ͑SECM͒ and X-ray photoelectron spectroscopy ͑XPS͒. The SECM measurements showed that the film grows rapidly on oxygen-free dehydrated copper ͑OF-HC͒ and that the rate depends on the substrate potential. The benzotriazole films were also observed on silver alloyed copper; however, electropolishing prevents film growth by enriching the surface with silver. XPS results show that the film consisted of ͓Cu͑I͒-BTA͔ on both materials. No evidence of ͓Ag͑I͒-BTA͔ was found.

“…It was reported by many researchers that the BTA -ion can adsorb onto the Cu surface to form an irreversible compact polymer film of [Cu(BTA)] n , which increases the inhibition efficiency dramatically in a certain potential region in aqueous solutions. [8,9,12,[35][36][37] Therefore, it is reasonable to assume that the observed surface Raman spectrum at 0.2 V comprised contributions from this irreversible polymer film attached to the Cu surface in a wide potential range, that is, the BTAH was adsorbed on the surface by the coordination of N atoms with Cu atoms. In the extremely positive potential region, the signal of the film decreased remarkably.…”

The surface coordination chemistry of benzotriazole (BTAH) on a Cu electrode was investigated by electrochemical synthesis of surface complexes and in situ electrochemical surface-enhanced Raman spectroscopy (SERS) in nonaqueous solution. Two different surface complexes were prepared in solution with or without triphenylphosphane (PPh 3 ). A new mixed-valence Cu-N cluster compound containing BTAH was synthesized by direct electrochemical oxidation of Cu in nonaqueous solutions with

Electrochemical and Quantum Chemical Studies of 1, 2, 3-Benzotriazole as Inhibitor for Copper and Steel in Simulated Tap Water

The corrosion inhibition effect of benzotriazole on copper and steel in simulated tap water was investigated by using potentiodynamic polarization, electrochemical impedance spectroscopy and a quantum chemistry analysis. The corrosion inhibition ef ciency for copper and steel was accordingly increased with an increasing of the benzotriazole concentrations. However, the electrochemical test showed a signi cant difference between the inhibition ef ciency of copper and steel. From molecular theory and the adsorption isotherm, the difference between the d-orbital structure of copper and steel affects the adsorption stability of benzotriazole on the metal surface. This postulation is well correlated with the results of the quantum chemical analysis.
