介孔分子筛的合成表征及催化性能(Ⅱ)rn——复合介孔分子筛的合成、介孔分子筛的表征和催化性能

摘要

介孔M41S材料的发现受到人们密切的关注,这是由于MCM-4 1分子筛可以合成出具 有规则1.5～10 nm孔径的孔道结构,MCM-41被认为可以应用于大分子的催化反应中,从而引 起 人们很大的兴趣。同时总结了配合物和介孔材料的组装、微孔和介孔复合材料的合成、MCM - 41分子筛的合成机理和表征、MCM-41分子筛的酸性和在不同反应中对大分子反应的催化性能。%The discovery of the mesoporous M41S materi als attracted considerable attention in particular due to the fact that MCM-41 can be synthesized into the structure with regular pore d iameters in the range of 1.5～10 nm.MCM-41 has been considered as very interest ing c atalytic material since it can be used for catalyzing large hydrocarbons and oth er molecules. T his paper summarized the assembly of complex and mesoporous materials, the synth e sis of composites of micro- mesoporous materials, the synthesis mechanism a nd the characterization of MCM-41 and catalytic performance in different reactio ns for large molecules.
