“…In order to optimize the performance of mesoporous silica in important applications, such as catalysis, separation, adsorption and ion-exchange, new synthetic chemicals have been introduced into their composition to alter their properties [1]. Recently, several new types of large-pore mesoporous silica materials, such as SBA-15, have been reported [2,3], where the material's structure and texture, especially the acidic sites, affect its catalytic properties [4].…”
