The mesoporous materials are prepared by the sol-gel process with the use of agents drivers or templates that are responsible to guide the inorganic skeletal architecture formation.
The materials were calcined in static air at 823 K for 2 h to remove the polymer template and to obtain white SBA-15 powder.
The materials were called SBA-15 (TEOS) and SBA-15 (CCB) as synthesed with TEOS or with CCB.
