The Structure and Properties of TiO(2)-Cu(II)-EDTA Ternary Surface Complexes.
The formation, composition, structure, and electrochemical properties of ternary surface complexes between copper(II) and ethylenediaminetetraacetate adsorbed on TiO(2) xerogels and on thin-film TiO(2) electrodes from solutions of varying pH have been studied by potentiometry, EPR spectroscopy, and electrochemical methods. The results strongly indicate that, in contrast to other organic ligands, B-type ternary surface complexes are formed in this system. The organic ligand forms an isolating layer between the surface of the TiO(2) electrode and the redox-active copper ions. Copyright 2001 Academic Press.
