doi:10.3724/SP.J.1077.2011.00134

Abstract

Abstract: Boehmite Sols were used as aluminum precursorsfor preparing mesoporous alumina with crystalline framework walls in thepresence of 1-butyl-3-methyl imidazolium tetrafluoroborate ([BMIM][BF₄]). T hestructureof theγ-Al₂O₃wasexamined by N₂ physicaladsorption, X-ray powder diffraction (XRD), transmission electron microscope (TEM), and solidstate ²⁷Al MAS NMR spectra. The results show that aluminawith the three-dimensional interconnected scaffold-like channels displays very richporosities with large mesopores, and the addition of [BMIM][BF₄]could improve the pore properties of alumina significantly.
