摘　　要：用浸渍法由高活性的电解γ-MnO2制得 γ-MnO2制得Ln2O3/γ-MnO2系列催化剂,并考察了其对CO、HC的氧化活性,测定了催化剂的比表面积.结果表明:Ln2O3/γ-MnO2的氧化活性及其比表面积呈现双峰趋势.Immersion method is used to prepare Ln2O3 / γ- MnO2 serial catalysts from the electrolyzed γ- MnO2 with high activity. The oxidation activities of CO and HC in the catalysts are investigated and their specific surface areas are measured respectively. The results show that the oxidation activities of Ln2O3 / γ- MnO2 and their specific surface areas present the double peak trends.
