Abstract The study investigates hydrogenation of CO 2 over mono- and bimetallic catalysts supported on biochar. In this reaction, iron–cobalt were shown to surpass monometallic iron cobalt in terms catalytic performance. optimal combination performance parameters was reached at an ratio 3 : 1. composition genesis the active phase Fe–Co catalyst identified, mechanism suggested for iron-dominated...

The semi-hydrogenation of alkynols to enols is a crucial process in the production pharmaceuticals, agrochemicals, fragrances, and flavors that involves complex set parallel consecutive isomerization hydrogenation reactions proceeds via several key intermediates. In view industrial importance large-scale enol through alkynol hydrogenation, various noble non-noble metal (e.g., Ni Pd)-based catal...

The hydrogenation of carbon-carbon double bonds is a classic application of homogeneous catalysis, and numerous complexes are known to catalyze it. Furthermore, the use of chiral ligands to produce enantioface selectivity in such catalytic hydrogenations is now well developed.1 The catalytic cycle for such reactions involves an olefin dihydride complex (with the addition of H2, step A, and the ...

Despite significant progress in the area of asymmetric hydrogenation, the enantioselective hydrogenation of aromatic and heteroaromatic compounds still remains a major challenge. Only a few examples with moderate enantioselectivity, which rely on unique catalyst systems and suffer from a limited scope of suitable substrates, have been described so far. There are several reasons that might expla...

Hydrogenation of unsaturated hydrocarbon compounds catalyzed by transition metals is traditionally believed to be a structure-insensitive reaction. However, recent progress in understanding the microscopic details of this process challenges the universality of this common belief. Recently, several examples of catalytic systems were described in the literature where hydrogenation of the olefinic...

The stepwise hydrogenation of the C=C bond and C=O group of acrolein on Au3 and Au5 model systems is investigated using the density functional theory(DFT) PW91 functional. Our results show that the C=C hydrogenation is more favorable than that of C=O bond on Au3 with the barriers of the rate-determining step being 0.35 and 0.62 eV respectively. On the other hand, the C=O reduction is preferred ...
