Abstract

Mesoporous Al-MCM-41 materials were synthesized using room temperature ionic liquid 1-cethyl-3-methylimidazolium bromide ([C₁₆mim]Br) as a single template and characterized by X-ray diffraction, N₂ adsorption-desorption, ICP-AES, ²⁷Al MAS NMR and TEM technique. These mesoporous materials exhibit hexagonal p6m pore architectures, and possess high surface area and narrow pore distribution. All aluminum in as-synthesized samples exists in tetrahedral coordination. Upon calcination nearly all aluminum still remains the tetrahedral coordination even when the Si/Al ratio is as low as 15. This indicates that the tetrahedral aluminum of Al-MCM-41 is stable.
