摘　　要：采用不同方法制备了五种活性氧化锰，并对它们进行了苯六酚氧化实验、锰氧分析、粉末ＸＲＤ分析和差热热重分析，测定了比表面积，指出组成与结构以及比表面积是影响活性氧化锰氧化活性的主要因素，为活性氧化锰的选择与使用提供了依据。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 MnO 2 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

关 键 词：活性氧化锰 组成 结构 氧化锰 比表面积
