摘要

合成了一系列新的MCM-41分子筛固载羧基钯（Ⅱ）配合物催化剂，并利用XRD、XPS、FT-IR和FT-Raman等技术对催化剂进行了表征。研究表明，MCM-41分子筛表面的Si—OH基可与三乙氧基硅烷类化合物发生作用，合成了表面羧基功能化的介孔MCM-41材料。 MCM-41分子筛在有机功能化过程中虽然其比表面积、孔容和平均孔径有所减少，但其孔结构未被破坏。MCM-41分子筛载体上的—COOH配体通过与Pd(OAc)2中OAc基的交换反应而与Pd2＋发生配位。

Abstract

A series of new carboxyl Pd（Ⅱ）complexes were prepared from organic silica via immobilization on MCM-41 molecular sieve

and characterized with XRD，XPS，FT-IR and FT-Raman techniques.The results showed that —COOH groups could be immobilized on the MCM-41 surface via a reaction of the silanol groups with oxyalky-silane compounds

and the organically modified MCM-41 materials retained its hexagonally-packed porous structure during supporting organic species

but internal surface area and pore diameter of the materials decreased markedly.The direct binding to silica surfaces was achieved by direct ligands exchange of MCM-41 supported caboxylate group ligands with Pd(OAc)2.
