3种还原剂对锰氧化物结构和形貌的影响

Effects of Three Kinds of Reducing Agent on Morphology and Structure of Manganese Oxide

锰氧化物的性能很大程度上受其形貌结构的影响。以高锰酸为氧化剂,乙酸锰、双氧水和硫酸锰为还原剂制备锰氧化物,对产物的结构、形貌和热稳定性分别用XRD、SEM、TEM和TG分析,讨论了不同还原剂对产物、结构、形貌和热稳定性的影响。

The performance of manganese oxide is largely influenced by its morphology and structure. In this paper manganese oxides are prepared with the permanganate as oxidizing agent, which is reacted with manganous acetate, hydrogen peroxide and manganese sulfate respectively. The structure, morphology and thermal stabilization of as- synthesized manganese oxides are characterized by X-ray diffraction （XRD）, scans electron microscopy （SEM）, transmission electron microscopy （TEM） and thermogravimentric analysis （TG）. The effects of different reducing agent on structure, mrphology and thermal stabilization of manganee oxides are studied as well.
