Abstract: Ordered mesoporous alumina was synthesized by sol-gel method with isopropoxide alumina as the source of alumina and PEO-PPO-PEO block copolymer F127 as the template. The results show that the mesoporous alumina surface area(480 m2/g), narrow pore size distribution(2—20 nm), and lange pore volume(over 1.2 cm3/g). Worm-like pore was formed and ordered to some extent. The structure of the synthesized sample was investigated by BET, TEM, and XRD technologies. The influence of various conditions on the structure of ordered mesoporous alumina was discussed.

Key words: PEO-PPO-PEO block copolymer F127, Ordered mesoporous alumina, High specific surface aera
