Abstract
Complex vanadium and titanium oxides modified by copper ions are studied by the electrochemical and ESR methods. Oxides Cu x V2−y Ti y O5−δ·nH2O (0<1.33) have a layered structure and oxides Cu x Ti1−y V y O5+δ·nH2O (0<0.25), an anatase structure. The intercalation of cations Cu2+ into the hydrates leads to oxidation of V4+. According to ESR data, V4+ exists in the oxides in the form of VO2+ and an octahedral surround of oxygen (V4+−O6), respectively. The electroreduction of ions of d-elements and chemisorbed oxygen in the oxides is analyzed. The intercalation of cations Cu2+ alters the content of V4+ and the chemisorption ability of the oxides. Possible reasons for this phenomenon are discussed.
