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.
The catalysts of Ln2O3 / γ-MnO2 were prepared by impregnation from γ-MnO2 with high activity and γ-MnO2. The oxidation activity of CO and HC was investigated and the specific surface area of the catalyst was measured. The results showed that Ln2O3 / The oxidation activity of γ-MnO2 and its specific surface area showed a bimodal trend.
