摘　　要：采用MnCl2,1,10-邻菲罗啉与1,6-萘二磺酸钠水热合成得到了具有二聚体结构的锰配合物[Mn（1,6-nds）（phen）2（H2O）]2·（CH3OH）3·（H2O）2（1,6-nds=1,6-萘二磺酸根离子,phen=1,10-邻菲罗啉）。在850℃下焙烧处理该配合物。采用X-射线衍射、热重分析和透射电子显微镜等手段表征了高温处理得到的产物。热重分析结果表明：该配合物的起始分解温度为185℃;X-射线衍射的结果说明焙烧后的产物是氧化锰;TEM表征结果表明：氧化锰纳米颗粒的直径在40~230nm之间。采用热分解二聚体锰配合物制备纳米氧化锰的方法具有效率高,简单和无污染等特点。The dimeric manganese complex [Mn（1,6-nds）（phen）2（H2O）]2·（CH3OH）3·（H2O）2 （1,6-nds=1, 6-naphthalene-disulfonate anion, phen=1,10-phenanthroline） was synthesized by the hydrothermal reaction of MnCI2, 1,10-phenanthroline and 1,6-naphthalene-disulfonate sodium. The complex was calcined at 850℃. After calcination, the product was characterized by the X-ray diffraction, thermogravimetric analysis and trans- mission electron microscope. The result of XRD displayed that the calcined product was manganese oxide. The result of TG showed that the initial decomposition temperature of the complex was 185℃. The TEM characterization result showed that the diameter of the manganese oxide nanoparticles was between 40 and 230nm. The preparation of nano-manganese oxide by the thermal decomposition of dimeric manganese complex was high efficient, simple and pollution-free.
