Catalytic combustion of ethyl acetate on supported copper oxide catalysts.

Abstract Total oxidation of ethyl acetate on supported copper oxide catalysts was investigated. The catalysts have been prepared by wet impregnation method and characterized by XRD, TEM and XPS. Among the catalysts with the supports of TiO 2 , CeO 2 /TiO 2 and CeO 2 –ZrO 2 /TiO 2 , CeO 2 –ZrO 2 solid solutions doped TiO 2 supported catalyst gives the highest catalytic activity. Catalyst with the composition of 5 wt.% CuO/10 wt.% CeO 2 –ZrO 2 –TiO 2 shows the total oxidation of ethyl acetate at about 270 °C with the 100% CO 2 selectivity. The characterization studies of supported copper oxide catalysts showed that the highly dispersed CuO is one of the active phase which contacts intimately with the support, the action of the interface between the components was not be ignored.
