Abstract

The invention belongs to the technical field of mesoporous materials, in particular to a green preparation method of a periodic mesoporous organic silicon oxide material. 2 S 2 o 8 In the solution, the unique micro-fluid effect and cavitation shock wave effect of ultrasonic waves are used to eliminate local concentration unevenness, accelerate the generation of hydroxyl radicals, and promote the hydrolysis of bridged organosilsesquioxane, and then combine with organic template agent P123 and water-soluble Non-toxic inorganic salts are mixed under ultrasound to promote the self-assembly process between organic templates and organosilicon sources; this method is carried out under neutral conditions without acid, alkali, and heavy metal ions, and will not produce acidity or alkalinity As well as the waste liquid containing heavy metal ions, the reaction process is green and pollution-free; the reaction has the advantages of high efficiency, mild reaction conditions, convenient operation, etc., which is beneficial to the application in large-scale production.

Description

technical field [0001] The invention belongs to the technical field of mesoporous materials, and in particular relates to a green preparation method of periodic mesoporous organic silicon oxide materials. Background technique [0002] Periodic mesoporous organosilica materials (PMOs) are a new type of organic-inorganic hybrid materials. Compared with traditional inorganic mesoporous silica materials, in addition to uniform pore size and high specific surface area, PMOs materials also have some new features, such as adjustable surface hydrophobicity / hydrophilicity, excellent water thermal stability and adsorption capacity, etc. In addition, the organic groups present in the PMOs framework structure can also be further functionalized to derive new functional groups. Therefore, PMOs materials show great application potential in many fields, especially in chemical industry (catalysis), environmental application (pollutant removal) and biomedicine (sustained drug release).
