WANG Gang, ZHAO Ruihong, GUO Fen, et al. Synthesis of organized mesoporous alumina by high gravity technology[J]. CIESC Journal, 2008, (5): 1310-1314.DOI:
Organized mesoporous alumina was synthesized in a rotating packed bed (RPB) by the traditional precipitation method.Aluminum nitrate was used as the source of aluminum
ammonium carbonate was used as precipitator
and polyethylene glycol 1540 (PEG 1540) was used as template.Then the effects of rotation speed
reactant mixing style
temperature and the addition rate of precipitator on the structure of mesopores were investigated.The experimental results indicated that the structure of mesoporous alumina was controlled by the high gravity technology.High surface area
narrow pore size distributions and ordered wormlike pores were obtained
and the high gravity technology had a significant effect on pore structure in the synthesis of mesoporous alumina.
