Synthesis of hollow mesoporous silica spheres and carambola-like silica materials with a novel resin sphere as template

Hollow mesoporous silica spheres with wormlike mesoporous were synthesized by a dual-templating method using resorcinol/formaldehyde resin spheres as hard templates and cationic surfactant (CTAB) as soft template. The average particles diameters were adjusted by changing molar ratio of TEOS/CTAB. Carambola-like silica materials with hollow structure can be obtained using one-pot method. (C) 2014 Elsevier B.V.
