  • Synthesis of catalytically active mononuclear and polynuclear compounds of Groups V–VIII metals (low-molecular clusters, giant clusters, and nanoparticles of these metals). Study of their physicochemical properties, particularly catalytic ones.
  • Production of branched structure hydrocarbons (high-octane components of motor fuel) from alcohols. Search for catalytic systems and selection of optimal process conditions.
  • Oxidative transformations of methane and higher alkanes into high-tech commercially valuable products (for example, dimethyl ether). Search for highly selective paths.
  • Theoretical and experimental study into the nature of the O–O chemical bond in complexes of coordination compounds and the mechanism of molecular oxidation reactions with peroxide compounds.Theoretical and experimental study.
  • Search for catalytically active compositions, including nanostructures, allowing for the conversion of greenhouse gases (methane and carbon dioxide), in order to obtain commercially valuable synthesis gas, hydrogen fuel, and electricity.

     New highly efficient and selective catalysts for carbon dioxide methane conversion were found. New contacts make it possible to create energy-chemical units that produce methane-based electricity and fuel hydrogen based, contributing to the transition fossil fuel-based vehicles to non-polluting ones.

     Fundamentally important research into the kinetics and mechanism of a series of reactions involving hydroperoxides were carried out, making it possible to get insight into the ways in which singlet dioxide and ozone coordinated by vanadium(V) are involved in the oxidation of hydrocarbon and perfluorinated alkanes, arenes, and alkenes. Quantum-chemical methods showed that the [V(ηO2)3]– triperoxocomplex isomerizes into unexpectedly more stable complex [V(=O)(ηO2)(O3)]–, which contains the O3 group as a bidentate ligand. This reaction was found to flow through two intermediate complexes, which can transfer both singlet dioxygen and an oxygen atom to the substrate molecule.

     Single crystals of more than 30 polynuclear complexes of divalent and trivalent metals of Group VIII, including palladium(II), platinum(II), nickel(II), cobalt(II), cobalt(III), iron(II), and iron(III) with carboxylate ligands, namely acetate, pivalate, isobutyrate, ad S(+)-2-methylbutyrate were first studied and characterized by X-ray diffraction.
