For the mechanism of N-hydroxyimide catalysed aerobic oxidation, we studied the effect of N-hydroxyphthalimide radicals reaction with emerging hydroperoxide, as this reaction affects the catalytic efficiency of hydroxyphthalimides. We obtained a kinetic equation that accounts for this reaction. For the system of manganese oxide with N-hydroxyphthalimide, we studied the relationship between catalytic activity and the content of the heterogeneous catalyst in the process of aerobic oxidation. The mechanism of homogeneous-heterogeneous catalysis was proposed, where the heterogeneous catalyst participates in the initiation stage. The obtained results are of scientific importance for the development of atom-efficient and ecologically benign techniques for processing of fossil and renewable materials into valuable products. We performed synthesis and studied properties of the heterogeneous nanostructured catalyst SiO2/CoFe2O4/SiO2/CuO. The mechanism of the heterogeneous Fenton reaction was proposed. We performed kinetic studies and determined the effective activation energy of the oxidation process. This catalyst was tested for the aerobic oxidation of the antibiotics Augmentin and Ampicillin. It was determined that active species, formed by molecular oxygen on the catalyst surface, produce hydroxyl radicals, which primarily participate in the oxidation of organic pollutants. Cross-linked polymer membranes were synthesized via UV-initiated radical copolymerization of acrylic monomers, which, according to their characteristics, can be used in low-temperature solid-state fuel cells. For the studied membranes, we determined proton conductivity, ion exchange capacity, thermogravimetric and mechanical properties. We investigated the effect of 8-hydroxyquinoline and α-picolinic acid on the stabilization of aliphatic peroxyacides. The catalytic decomposition of concentrated solutions of peroxyacetic and peroxydecanoic acids was studied in the presence of metal catalysts.
