Abstract
The catalysts for the combustion of ethyl acetate were prepared using Fe, Co, Cu, Cr, and Mn metal oxide as active components supported on Al 2O 3-Ce 0.5Zr 0.5O 2 mixed oxides and characterized by X-ray diffraction (XRD), temperature programmed reduction (TPR), oxygen storage capacity measurement, BET surface area, XPS measurement, and activity test. According to the results of characterization, it was found that Cu/Al 2O 3-Ce 0.5Zr 0.5O 2 (1:2, mass ratio) and Mn/Al 2O 3-Ce 0.5Zr 0.5O 2 (1:2) catalysts presented excellent activity for the catalytic combustion of ethyl acetate, because of the more reducible species and high reducibility of the catalysts. For ethyl acetate oxidation, more than 99% conversion was achieved at 245 °C over catalysts Cu/Al 2O 3-Ce 0.5Zr 0.5O 2 (1:2) and Mn/Al 2O 3-Ce 0.5Zr 0.5O 2 (1:2, mass ratio), indicating that the catalysts had great potential for wide use.
