Ln₂O₃/γ-MnO₂系列催化剂的氧化活性研究

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.

Abstract: 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.
