采用浸渍法制备了Pt/CeO 2-ZrO 2-Bi 2 O3催化剂，考察了催化剂上乙酸乙酯的完全氧化反应。Pt/CeO 2-ZrO 2-Bi 2 O3催化剂在低温下将乙酸乙酯完全氧化为CO2和H2O，不会形成乙醇和乙醛等副产物。乙酸乙酯氧化活性与载体的还原度相关，使得高还原度给出高活性。通过优化组成和Pt含量，在低至190°C的温度下，在10wt%的催化剂上实现了乙酸乙酯的完全氧化Pt/Ce0.63Zr0.17Bi0.20O1.90催化剂。
Complete oxidation of ethyl acetate over Pt/CeO2–ZrO2–Bi2O3catalysts prepared by a wet impregnation method was investigated. The Pt/CeO2–ZrO2–Bi2O3catalysts completely oxidized ethyl acetate into CO2and H2O at low temperatures without the formation of byproducts such as ethanol and acetaldehyde. The ethyl acetate oxidation activity correlates with the reducibility of the support such that a high reducibility gives high activity. By optimization of the composition and the Pt amount, complete oxidation of ethyl acetate was realized at a temperature as low as 190°C on a 10 wt.% Pt/Ce0.63Zr0.17Bi0.20O1.90catalyst.
