Synthesis of Regular Mesoporous MateriaLIn-situ on Montmorillonite

Abstract

Abstract: The long-ranged structure mesoporous materisLIs 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 800m²/g after being heated for 2h at 800℃ and 200m²/g after being heated for 2h at 1200 ℃. Mesoporous material can be formed in 2h at a temperature lower than 80℃.

Key words: Mesoporous material, Montmorillonite, Synthesis
