Abstract
Highly ordered mesoporous silica molecular materials are prepared using sodium silicate as a silica source, sulfuric acid and nonionic poly(alkylene oxide) surfactants or nonionic amphiphilic bloc copolymers as structure-directing agents. The mesoporous silica materials obtained have hexagonal and cubic structures, uniform pore size and high surface areas.
