A Novel Method for the Synthesis of Mesoporous Molecular Sieve MCM-41

XiuMeiTAI, HongXiaWANG, XiuQiSHI

Open publisher page 6 citations

Abstract

Using glycerol, glycol and water as solvent, cetyltrimethylammonium bromide (CTAB)as template, tetraethyl orthosilicate (TEOS) as silica source, ethylenediamine (EDA) as base source,mesoporous molecular sieve MCM-41 has been synthesized at room temperature, characterized by X-ray power diffraction and N2 adsorption. Compared with the samples synthesized by glycol and water, the samples synthesized by glycerol have larger pore diameter and high surface areas.Thus glycerol is an efficient solvent for preparing larger pore mesoporous MCM-41.
