    Catalytic Properties of a Novel Raney-Nickel Foam in the Hydrogenation of Benzene

    The catalytic properties of a novel Raney-Nickel mold were investigated in the liquid-phase hydrogenation of benzene and compared to commercially available Raney-Nickel. The novel Raney-Nickel catalyst showed ...

    Increased Conversion in the Heck Reaction Under Irradiation with Light

    Irradiation with light (UV–vis and visible) was shown to increase the rate of the Heck reaction at 90–140 °C using both heterogeneous and homogeneous catalysts. The photoreduction of Pd(II) is most likely the ...

    Abatement of NO Using Rhodium Catalysts Supported on Carbon Nanotubes: Carbon as Support Material and Reducing Agent

    The catalytic abatement of NO over rhodium catalysts supported on carbon nanotubes was studied. In the absence of oxygen, Rh/carbon nanotubes (CNT) catalysts exhibit high activities in the catalytic reduction ...

    Heck Reactions of Aryl Chlorides Catalyzed by Ligand Free Palladium Salts

    Palladium acetate has been shown to be a highly active catalyst for Heck reactions of aryl chlorides even in the absence of organic ligands. Bromobenzene can efficiently be coupled in presence of negligible tr...

    Controlled Distribution of Solid Catalysts into Two Immiscible Liquid Phases – Synthesis and Catalytic Applications

    A new concept for the separation of heterogeneous catalysts is presented. Against gravity, surface modified catalysts are located only in one of two immiscible liquid phases. The catalyst phase can be separate...
