A highly efficient copper supported catalyst for catalytic combustion of ethyl acetate

CeO2 and/or ZrO2 modified titania supports and the supported copper oxide catalysts were prepared by impregnation method using nitrate. Catalytic combustion of ethyl acetate has been measured in the temperature range 100-360 degrees C, and the structural and properties were characterized by means of TPR, XRD and XPS technologies. The results show that CeO2-ZrO2 modified TiO2 support highly enhanced the dispersion of CuO phase, resulting in improving the catalytic activity and suppressed the form of by-product such as ethanol and aldehyde. The complete decomposition of ethyl acetate was achieved at about 280 degrees C with the 100% CO2 selectivity. (c) 2005 Published by Elsevier B.V.
