mesoporous material (rus. мезопористый материал) — porous material, whose structure is characterised by the presence of cavities or channels with diameters in the range from 2 to 50 nm.


Among mesoporous materials the most interesting from a practical standpoint are ordered structures with a rather narrow pore size distribution. The chemical composition of such objects may be different, they include silicates and aluminosilicates (with such structures as MCM-41, SBA-15, etc.), materials based on titanium, zirconium, cerium, carbon materials, etc. The most common method for synthesis of mesoporous materials is based on the use of an organic template as a structure-forming agent, around which an inorganic framework is formed. The removal of the organic component leads to formation of pores, whose size is determined by the size of the initial template.

Mesoporous substances are used as catalysts, adsorbents, sensors , materials for optics, electronics and medicine. In nanotechnology mesoporous materials are used as matrices (nanoreactors) for the synthesis of nano-sized isolated particles, nanorods, etc.
