New approaches toward the generation of late first-row metal catalysts that efficiently facilitate two-electron reductive transformations (e.g., hydrogenation) more typical of noble-metal catalysts is an important goal. Herein we describe the synthesis of a structurally unusual S = 1 bimetallic Co complex, [((Cy)PBP)CoH]2 (1), supported by bis(phosphino)boryl and bis(phosphino)hydridoborane lig...

CoSi particles on a silica support, synthesized by metal organic chemical vapor deposition (MOCVD) of Co(SiCl(3))(CO)(4) as a precursor at atmospheric pressure and moderate temperature in a fluidized bed reactor, show high catalytic activity and selectivity in naphthalene hydrogenation.

The catalytic hydrogenation of CO2 to formate by Co(dmpe)2H can proceed via direct hydride transfer or via CO2 coordination to Co followed by reductive elimination of formate. The different nature of the rate-determining step in the two mechanisms may provide new insights into designing catalysts with improved performance.

The way in which the triple bond in CO dissociates, a key reaction step in the Fischer-Tropsch (FT) reaction, is a subject of intense debate. Direct CO dissociation on a Co catalyst was probed by 12C16O/13C18O scrambling in the absence and presence of H2. The initial scrambling rate without H2 was significantly higher than the rate of CO consumption under CO hydrogenation conditions, which indi...

The catalytic asymmetric hydrogenation of heteroarenes has been intensively studied during the last decade. Nowadays, various heteroaromatics, for example, indoles, pyrroles, and quinolines, can be reduced to the corresponding chiral heterocycles with high stereoselectivity through asymmetric catalysis. Glorius and co-workers recently found that a chiral N-heterocyclic carbene–ruthenium catalys...

in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

Context. Hydrogenation reactions of CO in interand circumstellar ices are regarded as an important starting point in the formation of more complex species. Previous laboratory measurements by two groups on the hydrogenation of CO ices resulted in controversial results on the formation rate of methanol (2002, ApJ, 577, 265 and 2002, ApJL, 571, L173). Aims. Our aim is to resolve this controversy ...

Correction for ‘Design of gold catalysts activation H 2 and H-donor molecules: transfer hydrogenation CO hydrogenation’ by Jhonatan Luiz Fiorio et al. , Catal. Sci. Technol. 2023, 13 3205–3215, https://doi.org/10.1039/D2CY01920E.

Platinum, palladium, and copper catalysts supported on precipitated silica have been studied for the hydrodeoxygenation and hydrogenation of 2-methyl-2-pentenal in the 200–400 C temperature range. The activity follows the order Pt > Pd > Cu. It has been found that at low temperatures, Pt and Pd are primarily active for the hydrogenation of the C@C bond to make 2-methyl-pentanal, with some decar...

In the present study, the effects of calcium doping on the performance of the co-precipitated Cu-MgO catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. The results proved that the addition of this promoter had a remarkable impact on the catalytic performance. The conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...
