| 摘 要： | 0引言自1992年Mobil公司制备出M41S系列1,2](包括MCM-41、MCM-48和MCM-50)介孔氧化硅以来,介孔材料以其有序度高、比表面积大、孔径可调等优异特性,引起了材料科学界的关注。不同类型的系列介孔材料,如SBA3]、HMS4]、MSU5]等相继见诸报道。其中,空间群为Ia3d的MCM-48型三维立方介孔氧化硅具有完全相同,但互不相连的两套孔道6],贯通性好,对称性高,对物料的传输优于二维孔道结构,在吸附、分离及催化等领域应用前景广泛。但这种结构对应的是溶致液晶相图的V1区域,对于多数表面活性剂来说,此相区较小,因此这种结构较难合成7]。…

| Abstract: | Highly ordered mesoporous silica HOM-5(cubic, Ia3d) with three-dimensional (3D) bicontinuous channels was fabricated under acidic condition via a direct-templating synthesis. Primary lyotropic liquid crystal mesophase of P123 was used as the template. The as-synthesized HOM-5 had thick walls of 15.0 nm. The mean pore diameter and specific surface area of the material were 5.7 nm and 500 m2·g-1, respectively. Results show that materials obtained from this simple synthesis are highly ordered with perfect meso-structures. The results of hydrothermal testing show that the as-synthesized silica retains Ia3d space group after refluxing in boiling water for 6 hours. |
