The aim of this work is to study the activity of new Pd catalysts, supported on two different nano structured carbon materials, for bromate catalytic hydrogenation. The influence of the support has been studied, obtaining the best results with a palladium ...
Monodispersed Pd-nanoparticles (similar to 8nm) prepared via a modified microemulsion method were deposited on active carbon fibers (ACF) fabrics and studied in a semi-batch 1-hexyne liquid-phase hydrogenation. The catalyst Pd(0.45 wt%)/ACF demonstrated > ...
Structured catalyst has been developed for C–C triple bond three-phase hydrogenation. The sintered metal fiber (SMF) coated by different oxides served as support for monodispersed Pd nanoparticles (6.4 ± 0.5 nm). The effect of acid–base properties and redu ...
The sorption kinetics in acetoxidn. of ethylene on a Pd catalyst is detd. and the application of the results in the design and optimization of heterogeneous catalytic reactors is discussed. [on SciFinder (R)] ...
Nitrogen-doped and un-doped carbon nanofibers layers, denoted as N-CNFs and CNFs respectively, coating the walls of cordierite monoliths have been used as support for Pd and Ru catalyst. They have been tested in bromate reduction in batch and continuous op ...
A combined DFT/vibrational spectroscopy approach is used to determine the interactions of the 1,3-dimethylimidazolium ([Mmim]+) and 1-ethyl-3-methylimidazolium ([Emim]+) cations and [BF4]- anions with each other in the liquid state and with Pd nanoparticle ...
Different glass fibers in woven forms were used as supports for Pt and Pd catalysts and were tested in toluene and CO total oxidn. at atm. pressure. The catalytic activity and the ignition-extinction temps. were investigated in relation to chem. compn. of ...
The use of transient methods to discriminate heterogeneous catalytic models was demonstrated for the catalytic epoxidn. of C2H4 on Ag and for the catalytic acetoxylation of C2H4 to vinyl acetate on a Pd catalyst. In sep. expts. the sorption kinetics on the ...
A study was made of the effect of the frequency and intensity of the gas oscillations on mass transfer between a gas and a solid surface, under conditions of a linear oscillation direction and a precisely defined surface shape, for the purpose of obtaining ...
A divergent total synthesis of three structurally distinct natural products from imine 9 was accomplished through an approach featuring: 1) a Pd-catalyzed decarboxylative cross-coupling, and 2) heteroannulation of 9 with bromoacetaldehyde and oxalyl chlori ...
