摘要
以KMnO4为锰源、抗坏血酸(AA)为还原剂,采用水热法制备系列纳米结构锰氧化物。通过调节反应物的物质的量的比、水溶液的pH值、反应温度和反应时间,制备出了不同纳米结构的锰氧化物,包括Mn3O4纳米粒子、MnOOH、α-MnO2和β-MnO2纳米棒。采用XRD和TEM测试技术对合成产物进行了表征,同时对其反应机理进行了探讨。
A versatile hydrothermal reaction between KMnO4 and ascorbic acid （AA） was developed to synthesize manganese compounds. A variety of nanostructured manganese oxides including Mn3O4 nanoparticles, MnOOH, α-MnO2 and β-MnO2 nanorods have been prepared through adjusting the molar ratio of the reactants, pH value of the aqueous solution, reaction temperature and reaction time. The products were characterized by X-ray powder diffraction（XRD） and transmission electron microscopy（TEM）. The possible reaction mechanism was discussed.
