High quality noncrystalline NiPB nanotubes were synthesized and exhibited high efficiency for the catalytic hydrogenation of p-chloronitrobenzene due to the characteristic confinement effect of the nanotubes.
An iron-catalyzed transfer hydrogenation of N-aryl and N-alkyl imines using isopropanol as the hydrogen donor is reported for the first time. A combination of two iron complexes serving different roles is the key for the success of this catalytic system. As a result, an environmentally friendly and precious metal-free transfer hydrogenation of imines has been developed. The use of a suitable co...
The hybrid material composed of palladium nanoparticles (PdNPs) functionalized with N-heterocyclic carbene ligands (NHCs) immobilized onto the surface reduced graphene oxide (rGO) results in an efficient catalytic towards hydrogenation and dehydrogenation N-heterocycles. rGO plays a dual role by acting as carbocatalyst acceptorless N-heterocycles support for facilitating its interaction molecul...
Asymmetric transfer hydrogenation over Ru-TsDPEN catalysts supported on siliceous mesocellular foam.
A siliceous mesocellular foam-immobilized Ru-TsDPEN complex exhibited excellent catalytic reactivity, enantioselectivity and reusability in the asymmetric transfer hydrogenation of an imine and ketones.
We have succeeded in preparing Au/Pd core-shell nanoparticles in apo-ferritin and improving the catalytic reactivity of olefin hydrogenation relative to Pd0 nanoparticles in the cage.
Levulinic acid and its esters are converted to γ-valerolactone over metal oxide catalysts by catalytic transfer hydrogenation via the Meerwein-Ponndorf-Verley reaction.
The hydrogenation of crotonaldehyde in the presence of supported platinum nanoparticles was used to determine how the interaction between the metal particles and their support can control catalytic performance. Using gas-phase catalytic reaction studies and in situ sum-frequency generation vibrational spectroscopy (SFG) to study Pt/TiO2 and Pt/SiO2 catalysts, a unique reaction pathway was ident...
