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.
