Abstract
In this work, surface analysis by measuring high-resolution Auger Cu L3L4,5M4,5 spectra was performed at very low take-off angles using X-ray photoelectron spectroscopy. The focus of this research was on determining if a fingerprint feature exists for a specific connection between Cu(I) (and/or Cu(II)) and different organic molecules. These organic molecules were adsorbed on Cu surface from 3Â wt.% NaCl solution containing a 1Â mM concentration of organic compound, i.e. 4âmethylâ2-phenylimidazole, benzotriazole, 3âamino-1,2,4-trazole, 1,2,4âtriazole, 2âmercaptobenzimidazole, 2âmercaptobenzoxazole, 2âmercaptobenzothiazole, 1âhydroxybenzotriazole, and 2-mercapto-1-methylimidazole. This feature was shown to be connected to Cu(I)- and/or Cu(II)-complex formation.
