| 摘 要： | 介绍了一种以环氧氯丙烷为凝胶促进剂,乙醇为溶剂的块状氧化钽气凝胶的合成工艺及气凝胶样品表征。氧化钽气凝胶的微观显微结构分别由场发射扫描电子显微镜(FESEM),高分辨透射电镜(HRTEM)给出,其孔结构及其分布由等温N2吸附实验给出。结果表明,气凝胶的骨架主要由粒径约1.5nm的初级颗粒构成,等温吸附结构表明,气凝胶主要是由微孔和中孔构成的BET比表面积为835m2/g气凝胶样品。

| Abstract: | The synthesis and characterization of the low-density monolithic tantalum oxide aerogel were investigated. The monolithic aerogels were prepared through the sol-gel polymerization of tantalum pentachloride in ethanol using epichlorohydrin as gelation initiators. The dried tantalum oxide aerogel was characterized by field emission-scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM) and nitrogen adsorption/desorption analyses. The aerogel network was determined to be... |
