The palladium-black-catalyzed electrogenerative hydrogenation of ethylene was investigated over partially wettable, porous, commercial electrodes between +0.6 and 0 V. In perchloric acid electrolyte, hydrogen io
Palladium-catalyzed transfer hydrogenation of some organic substrates in water containing a nonionic surfactant was examined using sodium hypophosphite as a hydrogen source. Hydrogenation of organohalides such as polychloroarenes, alkenes, alkynes, nitro compounds, aromatic aldehydes, and O-benzyl and N-...
Here we report an ambient electrochemical reduction of N2to NH3on carbon black-supported Pd nanoparticles (Pd/C), which can form Pd hydrides under certain potentials and promote surface hydrogenation reactions. Operating in a N2-saturated phosphate buffer solution (PBS) electrolyte, the Pd/C catalys...

Since it absorbs hydrogen, Pd is a critical component of the controversial cold fusion experiments that began in 1989. Organic synthesis When it is finely distributed, as with Pd on carbon, Pd forms a valuable catalyst in, for example, heterogeneous catalytic processes such as hydrogenation, ...
Palladium-catalyzed reactions have become an important tool in organic synthesis due to their high efficiency, selectivity, and diversity of possible transformations. Palladium-based catalysts have shown remarkable utility in coupling and hydrogenation reactions. However, despite their high activity, the hom...
