Materials characterized by high photocatalytic activity required for their use as effective photocatalysts of redox processes have been identified. For the first time, symmetric and asymmetric cationic, anionic and merocyanine polymethine dyes were used to sensitize TiO2. Spectral, electrochemical and energy characteristics of potential sensitizers are characterized. For the first time, the volt-ampere characteristics of a number of polymethine dyes were obtained, the regions of light sensitivity of the studied polymethines and their redox potentials in the excited state were determined. The photocatalytic activity of the obtained materials in the reactions of reduction of methylene blue and oxidation of potassium iodide has been established. The results of research of composite materials based on titanium dioxide, natural alumosilicates and synthetic phosphates, which have antibacterial activity, are presented. The influence of the methods of obtaining the studied materials on their phase composition and antibacterial action against pathogenic microorganisms Staphylococcus aureus and Escherichia coli was studied. It is shown that the created composite materials have high antibacterial activity against the above pathogenic microorganisms Product Description popup.authors Boruk Sergiy D. Vorobets Maria M.
