摘　　要：对硅基介孔材料的功能化改性进行了系统的分析调研.在概述硅基介孔材料基本性质和改性条件的基础上,总结了对其进行改性的三类主要方法及其改性原理,包括无机、有机、无机-有机复合改性.针对各类改性方法,详细综述了硅基介孔材料改性前后性质的变化特点,以及对重金属的吸附效果和吸附机理,并对改性硅基介孔材料吸附重金属的关键影响因素进行了探讨.The thnetional modification of silicon-based mesoporous materials is systematically analyzed.Based on an overview of the basic properties and modifiea6on conditionsof silicon- based mesoporous materials, three kinds of modification methods and their modification prin ciples are summarized, includes inorganic modified, organic modified, inorganic and organic compound modified.According to the eurrent research across the world ,the changes of the proper6es of silicon-based mesoporous materials by different modification methods are reviewed in detail, as well as the adsorption effet and adsorption mechanism for heavy metals. The key factors ＂,filleting the adsorption of heavy metals by modified silica-based mesoporous materials are also summarized.
