Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

DFT-Based Cu(111)||Cu2O(111) Model for Copper Metal Covered by Ultrathin Copper Oxide: Structure, Electronic Properties, and Reactivity

“…Recently, the pre-adsorption of 2-mercaptobenzothiazole (MBT) and 2-mercaptobenzimidazole (MBI) corrosion inhibitors at ultra low pressure on Cu(111) has been shown to markedly retard the oxidation kinetics. [35][36][37] Preprint accepted for publication in J. Phys. Chem.…”

The influence of the amino group in 3‐amino‐1,2,4‐triazole corrosion inhibitor on the interface properties for brass studied by ToF‐SIMS

“…The choice of which compound can be used or not is usually based on previous knowledge. However, to improve the existing knowledge of organic compounds as corrosion inhibitors, surface analytical studies significantly improve our understanding of how the corrosion inhibitor binds to the metallic surface, which is crucial for the effectiveness of the corrosion inhibitor 1–3 …”

“…On the contrary, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) requires much thicker surface layers to obtain spectroscopic information. 1,[4][5][6][7][8][9][10][11][12] In this work, the influence of the amino group in 1,2,4-triazole (TRI) in position 3, that is, 3-amino-1,2,4-triazole (3-AT) ( Figures 1A and 1E), is investigated in detail to explain whether and why it has an influence on the corrosion inhibition effect for brass in 3 wt.% NaCl solution. Brass is generally an important material for various applications [13][14][15][16][17][18][19][20][21][22][23] but corrodes considerably in chloride-containing solutions.…”

“…However, to improve the existing knowledge of organic compounds as corrosion inhibitors, surface analytical studies significantly improve our understanding of how the corrosion inhibitor binds to the metallic surface, which is crucial for the effectiveness of the corrosion inhibitor. [1][2][3] X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) are currently the most useful techniques for obtaining information on the adsorbate/metal interface and the type of adsorbate bonding. These two techniques (especially ToF-SIMS) do not require a high surface concentration of the adsorbate to detect it.…”

“…The use of GCIB complements and, in certain cases, significantly improves the information obtained by, for example, angle‐resolved XPS (ARXPS), which is limited to very thin surface layers. On the contrary, attenuated total reflectance Fourier transform infrared spectroscopy (ATR‐FTIR) requires much thicker surface layers to obtain spectroscopic information 1,4–12 …”
