Journal ArticleDOI
Platinum-catalyzed enantioselective hydrogenation of aryl-substituted trifluoroacetophenones
TL;DR: In this article, the hydrogenation of 2,2,2-trifluoroacetophenones with different aryl-substituents (CF 3, N(Me) 2 and Me) has been studied over Pt/Al 2 O 3 modified by cinchonidine.
Journal ArticleDOI
Electron microscopy and EXAFS studies on oxide-supported gold–silver nanoparticles prepared by flame spray pyrolysis
TL;DR: In this paper, gold and gold-silver nanoparticles prepared by flame spray pyrolysis (FSP) were characterized by electron microscopy, in situ X-ray absorption spectroscopy (XANES and EXAFS), XRD and their catalytic activity in CO oxidation.
Journal ArticleDOI
Pt-Ba/alumina NOx storage-reduction catalysts: Influence of Ba loading on NOx storage behavior
TL;DR: In this paper, a series of Pt-Ba/Al 2 O 3 catalysts, prepared by wet impregnation of Ba(Ac) 2, with Ba loadings in the range 4.5-28.5% were calcined at 500-°C in air and subsequently exposed to NO pulses in 5-vol.% O 2 /He atmosphere.
Journal ArticleDOI
Effect of Ba and K addition and controlled spatial deposition of Rh in Rh/Al2O3 catalysts for CO2 hydrogenation
TL;DR: In this article, the effect of Ba and K addition to Rh/Al 2 O 3 catalysts for CO 2 hydrogenation was investigated by using XRD and thermoanalysis combined with mass spectroscopy.
Journal ArticleDOI
Enantioselective hydrogenation of ethyl pyruvate. Influence of oxidative treatment of cinchonidine-modified platinum catalyst and hemiketal formation in alcoholic solvents
TL;DR: In this article, the authors investigated the reasons for the increase in the rate and enantiomeric excess after oxidative (aerobic) treatment of Pt/alumina in ethanol and demonstrated that this treatment results in the formation of acetic acid and consequently in the protonation of the quinuclidine n1 of cinchonidine.
