Mesoporous material

A mesoporous material is a material containing pores with diameters between 2 and 50 nm. Porous materials are classified into several kinds by their size. According to IUPAC notation, microporous materials have pore diameters of less than 2 nm and macroporous materials have pore diameters of greater than 50 nm; the mesoporous category thus lies in the middle. Typical mesoporous materials include some kinds of silica and alumina that have similarly-sized fine mesopores. Mesoporous oxides of niobium, tantalum, titanium, zirconium, cerium and tin have also been reported. According to the IUPAC, a mesoporous material can be disordered or ordered in a mesostructure. The first mesoporous material, with a long range order, was reported in the open literature in 1990, by Japanese researchers . Around that time, mesoporous materials were also developed by the group of the former Mobil Oil Company. The group filed a patent in January 1990 related to these materials. Since then, research in this field has steadily grown. Notable examples of prospective applications are catalysis, sorption, gas sensing, optics, and photovoltaics.
