Abstract:

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.

Key words: silica, mesoporous, synthesis, composites, adsorption
