Hybrid polymer-oxide materials based on transition metal oxides and polyvinylpyrrolidone have been obtained by non-stationary electrolysis on the surface of steel support. The elemental and phase compositions of the developed hybrid polymer-oxide materials have been investigated by XRF and XRD. The main phases are MoO 3 , MoO 2 , Mo 18 O 52 , Fe 2 O 3 , FeMoO 4 , NiMoO 4 , and CoMoO 4 . Using FT-IR spectroscopy, the incorporation of cobalt, nickel, iron, and molybdenum oxides into the structure of the polymer matrix has been proved. The surface morphology and surface height of the obtained hybrid polymer-oxide materials were reconstructed by electron microscopy and optical profilometry. Their thermal behavior was studied by comparing the DSC–TG curves of pure polyvinylpyrrolidone and the obtained hybrid polymer-oxide materials. The study of the catalytic activity in the hydrogen peroxide decomposition model reaction by the gasometric method showed that the developed hybrid polymer-oxide materials have high catalytic activity, and the presence of a polymer matrix leads to an increase in the catalytic activity of oxide phases in comparison with an oxide material of a similar composition in the absence of polymer. The study of the antibacterial activity of the obtained hybrid polymer-oxide materials showed their high efficiency against Staphylococcus aureus and Escherichia coli.
