Synthesis of Spherical Mesoporous SBA-15 with Abundant Carboxyl and Drug Release Profile
摘要
Abstract
Mesoporous SBA-15 spheres with abundant carboxyl were synthesized by a one-step method. The effects of CTES amount on the morphology, pore size and BET surface area of mesoporous SBA-15 were investigated. The samples were characterized by powder X-ray diffraction ( XRD) , scanning electron microscopy ( SEM) , infrared ( IR ) spectra and nitrogen adsorption/desorption techniques. The morphologies of as-obtained products are sphere-like. The materials possess highly ordered hexagonal mesoporous structure, large specific surface area and pore volume, and the pore sizes range from 0. 5 μm to 1 μm. The results show the pore size and the surface area of the materials decrease with the increase of the amount of CTES, obviously. The material has good assembly and drug delivery profiles. As-synthesized products have potential applications in catalysis, drug delivery and fillings for chromatography analysis.关键词
