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.
