Abstract

Abstract:

Alumina nanoparticles carrier was prepared by supersolubilizing self-assembly micelles. BET and mercury injection method were used to characterize the carrier and the influence of adhesive amount and template amount on pore character of nanometer alumina was researched. The results indicate that, when the amount of adhesive increased, surface area and bulk density increased, pore volume and pore size decreased. When the amount of template increased, pore volume and pore size increased, bulk density decreased. When template amount is greater 10 than benchmark, the surface area is 411.4 m²/g, surface area achieved maximum,less or more then this value, surface area would decrease.

Key words:

摘要： 采用超增溶胶团自组装方法制备纳米介孔氧化铝载体, 用BET 法和压汞法进行表征, 并研究了胶粘
剂用量和模板剂用量对所制备载体孔性质的影响。结果表明, 随胶粘剂含量的增加, 比表面积和堆积密度逐渐增
大, 孔容和孔径逐渐减小;随模板剂含量的增加, 孔容、孔径逐渐增大, 堆积密度逐渐减小, 而比表面积在模板剂含量
为基准+10 时最大, 达到411 .4 m2/ g , 模板剂含量过多或过少, 比表面积都会下降。
