The object of the research is catalytic system of transition metals (Ag, Co, Mn, Fe, Cu) with N-hydroxyimides for oxidation of organic substrates, polymer hybrid membranes based on acrylic monomers, magnetically separable catalyst embedded into nanostructured membrane for purification system. The research subject is catalytic oxidation of organic substances by oxygen using organocatalyst N-hydroxyphthalimide and a heterogeneous catalyst; synthesis and investigation of polymer membranes with proton-conducting properties; properties of nanostructured membranes with Fenton-like catalysts; influence of synthetic procedure on the membrane structure and purification efficiency. This work aims at the development of new catalytic systems based on metal oxides and N-hydroxyimides for the oxidation of organic substrates by oxygen via C-H bonds; synthesis of amphiphilic polymer hybrid membranes with high proton-conducting properties; creating of magnetically separable nanostructured membranes with Fenton-like catalysts. C-H bond oxidation model was created, which allowed modelling processes with heterogeneous catalysts, containing transition metal ions, in the aerobic oxidation of compounds with C-H bonds in benzylic groups. Сrosslinked polymer membranes were synthesized via UV-initiated radical copolymerization of acrylic monomers: acrylonitrile, acrylic acid and 2-acrylamido-2-methylpropanesulfonic acid with crosslinker N,N'-methylene(bis)acrylamide. The analysis of physico-chemical properties proved that these membranes can be used in low-temperature solid-state fuel cells. Films based on metal-polymer composite were synthesized using SAS of natural origin (rhamnolipids), which are highly efficient in purification of aqueous solutions from organic pollutants.
