Surfactant-Free Palladium Nanoparticles Encapsulated in ZIF-8 Hollow Nanospheres for Size-Selective Catalysis in Liquid-Phase Solution

Encapsulation of surfactant-free Pd nanoparticles (NPs) in the metal–organic framework material ZIF-8 hollow nanospheres was achieved. Pd@ZIF-8 hollow nanospheres showed excellent size-selective catalytic properties in the liquid-phase hydrogenation of olefins. As a result of the uniform pore size of the ZIF-8 shell (apertures of 3.4 ?), the catalyst showed high activity for the hydrogenation of 1-hexene (1.9×8.2 ?) but very low activity for larger molecules such as cis-cyclooctene (5.3×5.5 ?), trans-stilbene (4.2×11.3 ?), and triphenylethylene (9.1×9.2 ?). Other surfactant-free noble-metal nanoparticles could also be employed to produce NPs@MOFs for catalysis.

Metallic Barium: A Versatile and Efficient Hydrogenation Catalyst

Ba metal was activated by evaporation and cocondensation with heptane. This black powder is a highly active hydrogenation catalyst for the reduction of a variety of unactivated (non-conjugated) mono-, di- and tri-substituted alkenes, tetraphenylethylene, benzene, a number of polycyclic aromatic hydrocarbons, aldimines, ketimines and various pyridines. The performance of metallic Ba in hydrogenation catalysis tops that of the hitherto most active molecular group 2 metal catalysts. Depending on the substrate, two different catalytic cycles are proposed. A: a classical metal hydride cycle and B: the Ba metal cycle. The latter is proposed for substrates that are easily reduced by Ba0, that is, conjugated alkenes, alkynes, annulated rings, imines and pyridines. In addition, a mechanism in which Ba0 and BaH2 are both essential is discussed. DFT calculations on benzene hydrogenation with a simple model system (Ba/BaH2) confirm that the presence of metallic Ba has an accelerating effect.

HIGHLY SELECTIVE ELECTROCHEMICAL HYDROGENATION OF ALKYNES

Disclosed are electrochemical methods to prepare an alkane or an alkene, such as a cis- alkene, from an alkyne, or an alkane from an alkene. The method utilizes an electrochemical cell having a cathode and an anode and a reactor.
