Parahydrogen-induced polarization in alkyne hydrogenation catalyzed by Pd nanoparticles embedded in a supported ionic liquid phase

Parahydrogen-induced polarization was observed in the gas phase heterogeneous hydrogenation of propyne catalyzed by Pd-0 nanoparticles embedded in an ionic liquid phase supported on activated carbon fibers (Pd-0/SILP/ACF). The results were markedly different from those obtained with a reference catalyst, Pd-0/ACF, demonstrating the important role of the ionic liquid
