Morphological control of ordered mesoporous silica: formation of fine and rod-like mesoporous powders from completely dissolved aqueous solutions of sodium metasilicate and cationic surfactants
Abstract
Fine and rod-like silica-based mesoporous powders with very short diameter and length have been obtained through (1) the complete dissolution of both sodium metasilicate and cationic surfactants and (2) subsequent rapid pH-adjustment for the formation of silica-surfactant mesophase products.
