• The surface copper(II) species on a CuO/SiO<SUB>2</SUB> catalyst derived from binuclear copper(II) acetate monohydrate has been studied using XPS in comparison with that from the mononuclear tetraammine copper(II) complex. From the binding energy of Cu 2p<SUB>3⁄2</SUB> peak and the peak ratio of Cu 2p<SUB>3⁄2</SUB> and Si 2p together with the results by EXAFS, it was deduced that the highly dispersed one or two dimensional copper oxide cluster, which is interacted more weakly with SiO<SUB>2</SUB>, is developed on the copper(II) acetate monohydrate derived catalyst.
