Tuning the Pore Size of Monodisperse SBA-15 Spheres

Abstract:

A flexible, controllable and facile synthesis route was presented in the synthesis of spherical particles of mesoporous SBA-15 with diameter up to 28 nm, and particle diameter of 3-5 µm. The structures and morphology of these materials were characterized by powder X-ray diffraction (XRD), nitrogen adsorption analysis and scanning electron micrographs (SEM). The relationship between the porous property of silica and the weight ratio of starch to TMB were discussed. It indicates that the weight ratio of starch to TMB have a significant effect on the pore size, the surface area and also contribute to a narrow pore size distribution.
