Hydrophobic MCM-41 was prepared by surface modification technique. The basic idea is to bind an alkyl substituent chemically to the surface of pure silica MCM-41 via an organic reaction. The hydrophobic MCM-41 was halogenated and reacted with alkyl group. These materials were characterized by using XRD, N2 physisorption, thermal analysis, and FT-IR. Alkyl substituted samples exhibited well-defined (100) reflections and showed uniform pore size and high surface area after substitution reaction. Substitution of alkyl group to MCM-41 was confirmed by FT-IR spectroscopy and amount of alkyl group was measured by thermal analysis. |
