Study on the regulation mechanism of tunable characteristics of porous silica microspheres synthesized via micelle templating method
Source abstract
Abstract
In this study, amorphous porous silica microspheres (PSMs) were synthesized by the micelle templating method. The effects of cationic surfactants with different alkyl chain lengths and molar masses on the tunable characteristics of PSMs were systematically investigated under alkaline and mild conditions. By increasing the alkyl chain length and the molar mass of the cationic surfactant, PSMs with sizes adjustable from 930 to 158 nm and average pore sizes tunable from 1.8 to 3.3 nm were obtained, and the inter-particle dispersity was also improved. This study provides a mechanism for regulating PSMs by cationic surfactants, suggesting that the particle size and pore size are related to the silica-surfactant micelle concentration and micelle size, respectively. In addition, it visually confirms the key role of cationic surfactants in the spherization process by comparing the morphology of the products before and after adding cationic surfactants.
