【摘要】用溶胶-凝胶法制备 Mn₃O₄/Tm₂O₃复合纳米材料; 应用 X 射线粉末衍射仪（XRD）, 透射电子显微镜（TEM）, 红外光谱分析方法（FTIR）等手段对样品进行表征,得出纳米粒子为四方晶系,平均粒径为 38.0nm; 并研究了碱型 Mn₃O₄/Tm₂O₃ 复合纳米材料对有机农药甲胺磷的催化增敏作用, 结果表明质量比 Mn:Tm=100:0.1 与在400℃下灼烧 2h 的纳米材料的催化增敏作用最佳.更多还原

【Abstract】 The Mn₃O₄/Tm₂O₃ and basic Mn₃O₄/Tm₂O₃ nanoparticles were prepared by a Sol-Gel method.The powder is characterized by XRD,TEM and FTIR,showing that the powder is Mn3O4 square crystalloid,and the average diameter is 30.8nm.The effect of catalyst were studied on the increase sensitivity of methamilophos, it was found out increase sensitivity best when mMn : mTm= 100.0 : 0.1and be calcinated under 400℃ for 2 h..更多还原
