| 摘 要： | 以(Mg(NO3)2·6H2O, (NH4)2CO3 和NH3·H2O为原料,采用两种离子交换树脂均匀沉淀法分别制备MgO纳米粒子.用热分析、X射线粉末衍射(XRD)、透射电子显微镜(TEM)、高分辨电子显微镜(HR TEM)、选区电子衍射(SAED)和BET等对所制备的MgO粒子进行了表征.结果表明:经700 ℃焙烧后制备的MgO纳米晶体属六方晶系,样品分散性较好,平均粒径约为25 nm;MgO纳米晶体清晰、有序的电子衍射点阵,表明晶体的结晶度较好;纳米粒子a和b的比表面积分别为31 m2/g and 32 m2/g.

| Abstract: | MgO nanoparticles was prepared by exchange resin homogenous precipitation methods using Mg(NO3)2·6H2O, (NH4)2CO3 and NH3·H2O as raw materials. The MgO nanoparticles was characterized and analyzed by thermo-gravimetric (TC) analysis, infrared (IR) spectrum analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR TEM), selected area electron diffraction (SAED) and the bet method (BET). The results indicated that the particles a and b calcined at 700 ℃ had a clear crystal lattice and hexagonal shapes with average 25 nm in diameter, the As with 31 m2/g and 32 m2/g, respectively. |
