不同结构粉状纳米材料的透射电镜表征

Characterization of different structures nano-powders by transmission electron microscope

使用透射电镜对纳米氧化锌、纳米氢氧化镁、介孔分子筛的形貌进行表征,得出粉状纳米材料制备工艺与结构的关系。采用超声波细胞粉碎仪超声分散粉状纳米材料制备透射电镜样品,使分散性更好。

The particle morphology of nano-sized zinc oxide, magnesium hydroxide, mesoporous molecular sieves were characterized. The relation of preparation technology and structures were acquired. To get better dispersibility,Ultrasonic crasher was used for TEM specimen preparation.
