CARBON NANOTUBES, HETEROGENEOUS CATALYSIS, HYDROGENATION, GRAPHENES, ACID-BASE CATALYSIS The main goal of the work was to develop the physico-chemical principles of creating catalysts based on carbon nanotubes (CNTs), reduced graphene oxide (GOG), carbon dots (CT) and composites based on them for the processes of hydrogenation of hydrocarbons and carbon monoxide, acid-base transformations, and - and polyhydric alcohols. As a result of the work, methods for the synthesis of nanocomposites containing carbon nanotubes, oxides (Al2O3, TiO2) and HZSM-5 zeolite were developed, and a method for the synthesis of Ni@BNT, Pt@BNT nanocomposites by impregnation was proposed. For the first time, the catalytic activity of CNTs and VOGs in the direct dehydrogenation of ethane was demonstrated. It was shown that BNT is a more active but less selective dehydrogenation catalyst compared to VOG. The effect of the size of platinum nanoparticles in Pt@BNT composites on the rate of carbon monoxide hydrogenation reaction was revealed. It was shown for the first time that the diffusion of C1–C3 alcohols on CNTs is not "accelerated". It has been established that the conversion of methanol on CNT-based composites takes place by two independent routes: methanol dehydration at the active centers of the oxide component and methanol dehydrogenation on the CNT surface. It was established that the modification of titanium oxide with sulfo groups and carbon nanotubes allows to obtain a selective catalyst for the conversion of glycerol into linear short-chain polyglycerides.
