The synthesis of hybrid biochars obtained by the method of mechanochemical activation and pyrolysis of industrial waste (lignin and blast furnace magnetic dust) was developed for use as a sorbent for the dye methylene blue. The studied materials can be used as effective selective adsorbents for the removal of organic substances from aqueous solutions in water and wastewater treatment technologies. In order to create new biologically active nanocomposites consisting of gold nanoparticles and metal-containing boron clusters (Au NPs/ COSAN thiophosphate), the idea of attaching metallocarborane to the surface of gold NPs through the thiophosphate group was implemented, which was confirmed by the methods of absorption spectroscopy and dynamic light scattering. Investigation of the antimicrobial activity of colloidal solutions of silver nanoparticles stabilized by quercetin. Mesoporous TiO2 and TiO2/Wn+ nanosized films were synthesized by the sol-gel method and applied to glass and metal substrates (food grade steel 08X18N0, titanium foil). Addition of titanium dioxide with tungsten up to 5% increases the corrosion resistance of the coating and prevents corrosion of the substrate during exposure for 1000 hours in the "salt cabinet". The photocatalytic conversion of lignin obtained from sorghum (Camelina sativa) with the participation of films of titanium dioxide and iron titanates was studied. It was shown that the products of lignin conversion with the participation of nitrogen-containing iron titanate films exhibit the highest antioxidant activity when exposed to visible light. The fundamental "property-structure" relationships obtained in the work can be used in the creation and operation of functional hydrophobic coatings, in particular for the protection of porous silicate building materials from the negative effects of environmental factors in operating conditions.
