摘　　要：透射电子显微镜由于其高分辨率广泛应用于材料研究中。利用透射电镜对材料进行表征,可以更好地研究材料的微观结构特征,揭示宏观现象与介观和微观结构间的关系,并开发出具有特异性能的新材料。本实验用苯甘氨酸衍生物为模板制备出类似硅藻结构的纳米介孔二氧化硅,用透射电子显微镜研究了反应组成的变化对硅藻结构的介孔二氧化硅纳米材料制备和形貌结构的影响。Transmission electron microscopy is widely used in the materials due to the high resolution. Using the TEM ,you can make an intensive study in the microstructure of the materials and reveal the rela‐tionship between macroscopic phenomena and microstructure. Herein ,the template is phenyl glycine deriv‐atives. The mesoporous silicas were prepared through templating approaches ,which were characterized u‐sing transmission electron microscopy. Then ,we studied the preparation and structure of the mesoporous silicas with different conditions.
