FIELD: chemistry.

SUBSTANCE: catalytic materials consist of special hybrid combinations of inorganic/polymer compounds, which contain metal nanoparticles. They are suitable, in particular, for hydrogenation of substituted α-, β-unsaturated acids or esters. Catalytic material consists of metal oxides and organic polymers with hydroxyl groups, in which: 1) metal oxides are chemically bound with organic polymer by means of their hydroxyl groups, 2) metal particles with catalytic activity in chemical reactions are immobilised with hybrid compound, and 3) metal particles with catalytic activity are not only on the surface, but also inside hybrid compound. The invention also relates to methods for obtaining catalytic material. According to one method: 1) hybrid compound is synthesised by neutralisation of silicate with acid in solution, which contains organic polymers with hydroxyl groups, with the following removal of solvent, 2) synthesised hybrid compound is submerged into solution or is subjected to application on it of solution of metal salts particles with catalytic activity, with further reduction to transform absorbed salts into metal particles. According to other method: 1) hybrid compound is synthesised by neutralisation of salts of metal particles with catalytic activity and at least one salt, selected from zirconium salt and oxyzirconium salt, with alkali in solution, which contains organic polymers with hydroxyl groups, with further removal of solvent, or bringing solid mixture of organic polymers with hydroxyl groups, salts of metal particles with catalytic activity and salt, selected from zirconium salt and oxyzirconium salt in contact with alkali solution; and 2) synthesised hybrid compound is reduced to transform salt of metal particles with catalytic activity into metal particles.

EFFECT: materials can be easily applied repeatedly with negligible small leaching of catalysts.
