Meso, has been adopt by IUPAC to defined porous materials with pore sizes between 2.0 and 50.0 nm SBA-15 Mesoporous Silica Is extensive area for many research, such as adsorption, chromatography , separation, catalysis, drug delivery, sensors, and gas storages. because it has large specific surface areas (500-1000m2g-1), pore sizes (from 2 to30 nm), high hydrothermal stability, thick framework walls. Furthermore, the possibility to modify their chemical surface with different organic functional groups.
