POROMETRIC TITANISILICA WITH HIGH CONTENT OF ISOLATED TITATINIUM ATOMS, METHOD FOR ITS RECEIVING AND METHOD FOR RECEIVING HOMOGENOUS MESOPOROUS TITANOSILICA

摘要

Poromeric titanosilica contains isolated titanium atoms and is characterized by high specific surface. The content of isolated titanium atoms is more than 5 mol %. They are mainly in tetrahedral site and uniformly dispensed in the inorganic matrix. The method for receiving a porometric titanosilica includes the carrying out carboxethyl ester hydrolysis in the water mixture with organic solvents with next drying-out and roasting the material. The method for receiving of homogenous mesopore porometric titanosilica is also claimed. The invention provides receiving the porometric titanosilica with high specific surface and high content of isolated titanium atoms.
