| Abstract: Five kinds of active manganese oxides were prepared with different methods. he benzenehexol-xoidizing experiments were done to them. It appeared that different samples have different oxidizing activities. The manganese-oxygen analyes were also done. Their X-ray power diffraction spectras, specific surface areas and DTA-TGA curves were determined. All the resutls were compared with β-MnO2. This paper pointed out that composition、structurer and specific surface area are the three factors that affect the oxidizing activity of manganese oxides. It provides some theoretical and practical foundation for the selectivity and utility of active manganese oxides. |
