It has been shown by X-ray diffraction analysis, EXAFS and XPS methods and in experiments on the low-temperature oxidation of CO that two types of catalytic oxidation centres are formed during sol–gel synthesis of single-phase Cu–Ti oxide systems (0.5–5.0 mass% Cu) based on anatase: the first type involves Cu+ ions in the [111] crystal planes, while the second type involves Cu2+ ions, which isomorphically substitute titanium ions in the [100] planes of TiO2.
