Synthesis and Charaterization of 3-aminopropyl Modified Mesoporous Silica MCM-41 at Room Temperature

Abstract

Abstract: Under mild experiomental conditions, with 3-aminopropyltriethoxysilane as the coupling agent, mesoporous molacular sieve MCM--41(Si/Al=35) was modified,
and --(CH₂)_3NH₂ organic functional group was successfully introduced into the pore of the mesoporous sieve, the organic/inorganic complex material MCM--(CH₂)₃NH₂
was synthesized, and characterized by XRD, FTIR, DTA-TG, nitrogen adsorption-desorption at 77K and HREM. The results of the characterization show that --(CH₂)₃NH₂
not only gets into the modified inner wall of mesoporous MCM-41, but also makes MCM--41 remain its ordered pore structure.

Key words: MCM--41, modified, 3-aminopropyltriethoxysilane, MCM-(CH₂)₃NH₂
