AbstractThe reasonable conversion of renewable resources such as biomass to fuels and chemical materials is vital important section for the natural carbon cycle and the effective solution for sustainable use of our planet’s resources. The process of syngas (from biomass gasification) to higher alcohols is an atomic efficiency reaction pathway and i...

AbstractTrends in the influence of a proton-donor solvent on the reaction of aminolysis of ethylene carbonate, which proceeds through concerted and stepwise mechanisms, are studied. The study is based on kinetic data of model reactions in alcohol solutions and results of DFT quantum chemical calculations of reaction paths that involve hydrogen-bond...

AbstractFunctionalized aromatic amines are an important basis for the production of pharmaceuticals, agrochemicals, polymers, dyes, and other industrially significant products. The catalytic reduction of nitroarenes to aromatic amines is one of the methods most commonly used for the production of amines both in industry and in the laboratory. In th...

AbstractThe structure of Pd–Ag/Al2O3 samples with different Ag/Pd ratios has been studied by a complex of physicochemical methods (H2-TPR, XRD, H2-TPD, TEM). Catalysts have been synthesized by supporting an active component on α-Al2O3 and γ-Al2O3. X-ray diffraction analysis has revealed the formation of a Pd–Ag substitutional solid solution with a ...

AbstractThe results of 60 years' research into the mechanisms of olefin oxidation catalyzed by palladium complexes (Wacker oxidation) are analyzed. The concepts of the mechanisms of related oxidative carboxylations (Moiseev reaction) and alkoxylations are discussed. This review considers the regularities of processes in aqueous organic solvents; th...

AbstractCatalysts based on manganese oxides, doped with Pt, and supported on ceramic monoliths with a honeycomb structure were produced by impregnation and solution combustion synthesis (SCS). In SCS, glycine was used as a fuel additive, ensuring different conditions of the combustion of depleted (φ 1) fuel mixtures. The catalysts were studied by ...

AbstractThe catalytic activity of glutathione-stabilized gold thiolate nanoclusters (1–2 nm) in the oxidation of methane with H2O2 and air oxygen in aqueous medium at 70°C in 30 atm CH4 was studied. The ratio and yield of the oxidation products CH3OH and CH3OOH depends on the content of H2O2 and oxygen in the reactor. At increased partial pressure ...

AbstractPlatinum catalysts supported onto bayerite alumina were synthesized and studied. Alumina of the θ-Al2O3 type, which was prepared from metallic aluminum by an aluminate method, was used as a support, and platinum(IV) nitrate and hydrogen hexachloroplatinate(IV) precursors containing Pt4+ ions were used for supporting an active component. The...

Abstarct—Mechanochemical synthesis in a ball mill was applied for the nanocomposite Cu(CuO)–CeO2 catalyst preparation from CeO2 and following dopants: Cu metal and copper oxides of different morphology and composition (CuO pure and CuO containing 4 or 16.5 wt % of Cu2O). The materials obtained were examined with the use of X-ray phase analysis, sca...
