NANOCOMPOSITE MATERIAL AND METHOD OF PRODUCING SAID MATERIAL Russian patent published in 2011 - IPC B01J20/02 B01J20/30 B01J27/14 C01B37/02 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to inorganic chemistry, particularly to synthesis of porous nanostructures. Disclosed is a composite material containing an active phase in form of a heteropolyacid and/or its salt, which is incorporated into a matrix of a porous inorganic carrier in which the active phase has the form of nanoparticles, the heteropolyacid anion of which is bonded to structure-forming elements of the matrix through an ion bond and is incorporated into the matrix during its synthesis in situ. The invention also discloses a method of producing the material, according to which incorporation of the heteropolyacid into pores of the carrier takes place during synthesis of the matrix of the porous carrier in situ through reaction of an alkoxide of the structure-forming element of the synthesised matrix with the heteropolyacid and/or its salt in the presence of a salt of the same or of another structure-forming element of the matrix, homogenisation of the system to obtain a sol, gelling the sol, maturing the sol and thermal treatment of the sol.

EFFECT: invention enables to obtain stabilised nanocomposite material with high thermal stability and high acidity, the active phase of which is tightly bound to the carrier.
