摘　　要：硅基介孔材料是一类具有“里程碑式”意义的新兴材料,其具有可调孔径、高比表面积、有序孔体系、易于功能化的稳定骨架等独特的结构和性能。发展至今,这些材料应用领域仍在不断扩展,尤其在吸附废水中的污染物和金属分离方面有着显著的优势。本文首先简要介绍了硅基介孔材料的研究工作,其中M41S和SBA系列介孔材料的研究最为广泛;综述了硅基介孔材料的制备要素,包括模板剂、硅源、合成条件,以及三者之间的相互作用对材料合成的影响;材料改性是研究的热点,对无机、有机和其他改性三个部分的研究工作做了总结,阐述了功能化修饰在材料的结构和性能方面的作用;最后探讨了这些材料在金属吸附方面的应用及其对金属的吸附特性和机理,并展望了硅基介孔材料在合成和应用方面的发展方向,为其在实际中的工程应用提供理论依据。Silicon-based mesoporous materials are an emerging class of“milestone”materials with unique structure and properties such as tunable pore size,high specific surface area,ordered pore system and stable backbone for functionalization.So far,the application fields of these materials are still expanding,especially they have significant advantages in the adsorption of pollutants in wastewater and metal separation.Firstly,the research work of silicon-based mesoporous materials was briefly introduced,among which M41S and SBA series were the most widely studied.The preparation factors of silicon-based mesoporous materials,including template agent,silicon source,synthesis conditions and the effects of their interactions were reviewed.Material modification was inevitable.This paper summarized the research work of inorganic,organic and other modifications,and explained the function of functional modification on the structure and properties of materials.Finally,the application of these materials in metal adsorption and their adsorption properties and mechanisms were discussed,and the development direction of the synthesis and application of silicon-based mesoporous materials was prospected,which provided a theoretical basis for the reference in practical engineering.
