The catalysts for the combustion of ethyl acetate were prepared using Fe, Co, Cu, Cr, andMn metal oxides as active components supported on Al2O3-Ce0.5Zr0.5O2 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/Al2O3-Ce0.5Zr0.5O2 (1:2, mass ratio) andMn/Al2O3-Ce0.5Zr0.5O2 (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 ℃ over catalysts Cu/Al2O3-Ce0.5Zr0.5O2 (1:2) and Mn/Al2O3-Ce0.5Zr0.5O2 (1:2, mass ratio), indicating that the catalysts had great potential for wide use.
