Mesoporous solids
Mesoporous solids [ meso (Greek) = in between, in the middle] are porous materials with pore diameters between 2 nm and 50 nm according to the IUPAC definition . The first materials were silicates of the so-called MCM family ( MCM-41 etc.) and were made in the early 1990s Manufactured by researchers from the Mobil Oil Group ( Charles T. Kresge , abbreviation MCM for Mobil Composition of Matter).
Classification of porous materials according to their pore size:
microporous: pores <2 nm
Mesoporous: pore size between 2 and 50 nm
macroporous: pores> 50 nm
