An X-Ray Photoelectron Spectroscopy (XPS) Study of Activated Carbons Impregnated with Some Organocopper Complexes

Five organocopper complexes were impregnated on an activated carbon surface, and the surface composition of the resulting impregnated carbon investigated by X-ray photoelectron spectroscopy (XPS). From surface composition, and the high-resolution C(1s) and Cu(2p(3/2)) XPS spectra, the ratios of O/Cu, N/Cu, F/Cu and C/Cu could be calculated. It was found that three of the complexes were either unstable or decomposed on the carbon surface. This evidence could only be obtained by XPS technique, and the analytical method employed in this report. Activated carbon, Organocopper complexes, X-ray Photoelectron Spectroscopy (XPS)
