Реферат: In this work we report a comparative study of two types of nanoparticulate catalytic systems based on two amphiphilic block copolymers and a nanoporous polymer, hypercrosslinked polystyrene (HPS). Nanostructures in polymers (block copolymer micelle cores or nanopores) control nanoparticle (NP) formation and location while polymeric environment (functional groups) influences the catalytic performance. Catalytic properties of these nanocomposites were studied in selective hydrogenation of triple bond of dehydrolinalool and in direct selective oxidation of two monosaccharides: L-sorbose and D-glucose. In hydrogenation, the highest selectivity of 99% was achieved for Pd, PdZn, PdAu, and PdPt catalytic NPs in polystyrene-b-poly(4-vynyl pyridine) micelles due to a modifying influence of pyridine units, while the highest activity of 49.2 mol LN/(mol Pd· s) was observed for the PdPt NPs due to synergy of catalytic activity of both metals in hydrogenation. In oxidation of L-sorbose and D-glucose, the highest activities were observed for the Pt and Ru catalysts, respectively, based on HPS due to better access of catalytic sites of NPs.
