摘要：
The functionalized SBA-15 with quaternary ammonium organic group was directly synthesized in acid conditions by using nonionic triblock P123 as template, N-trimethoxysilylpropyl-N,N,N-tiimethylammonium chloride (TMAPS) as modifying agent. By means of XRD, TEM, N-2 adsorption-desorption and Raman spectroscopy, the structure and properties of the functionalized SBA-15 were characterized. The results indicated that the regular hexagonal structural character was retained after the functionalization. With increasing of amounts of TMAPS, the BET surface area, pore size, and pore volume of functionalized. SBA-15 were decreased. Moreover, Au-SBA-15 had been successfully prepared by ion exchage of TMAPS groups uniformly distributed in the channel of functionalized SBA-15 with HAuCl4.
