摘要
The long-ranged structure mesoporous materisl is obtained by using solution silicate and surface silicate as Si and Al sources and CTAB as the template at a low temperature for a short time. The effect of the crystallization time, crystallization temperature and the acting time of NaOH was discussed through XRD, nitrogen adsorption and TEM. The samples synthesized have a high thermal stability. The specific surface areas remain more than 800 m 2/g after being heated for 2 h at 800 ℃ and 200 m 2/g after being heated for 2 h at 1 200 ℃. Mesoporous material can be formed in 2 h at a temperature lower than 80 ℃.
