摘　　要： 硅基介孔材料作为一种新兴的固体多孔材料,不仅具有孔道大小均一、排列有序、孔径可以在2—50 nm内连续调节等重要特征,而且还具有较大的孔容、高的比表面积、孔道表面可进行物理吸附或化学修饰及较好的水热稳定性等特点。其在吸附分离、催化、生物材料、药物缓释等方面,以及光、电、磁等领域都具有广阔的前景,是目前材料领域的研究热点。系统综述了近年来M41S,HMS,MSU,SBA,杂原子化等系列硅基介孔材料的国内外研究现状,重点讨论了硅基介孔材料的分类、合成技术和机理、应用领域及目前存在的问题和未来的发展方向。 As a novel solid porous material, silica-based mesoporous is characterized by uniform and orderly pore size, and the pore diameter can be adjusted continuously in the range of 2-50 nm, which is also featured by large pore volume, high specific surface areas, orderly and adjustable pore structure, high hydrothermal stability, and the surface of mesoporous channel can be modified by physical adsorption or chemical modification. It is of much use in the fields of adsorption-separation, catalyst, biomaterial, drug slow-release, photochemistry, electrochemistry, magnetochemistry, and it is one of hot spots in the research of materials field. The recent-year advance of silica-based mesoporous materials like M41S, HMS, MSU, SBA, hybridizedatom at home and abroad was reviewed. The classification, synthesis technique and mechanism were investigated. Furthermore, the potential application and existing problems were discussed, and the future development directions were forecasted.
