Abstract

We will show that metallic and bimetallic nanoparticles solubilized in 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquids (IL) can be used as catalysts for a variety of oxidation and hydrogenation reactions. Nanoparticles were either directly synthesized in the IL or transferred to the IL from other solvents. Characterization was carried out by UV-Vis spectroscopy and transmission electron microscopy. Both the activity and selectivity of the hydrogenation reactions could be tuned by varying the composition of AuPd bimetallic nanoparticles. We will also show that the nanoparticle/IL catalysts can be recycled and then reused for further catalytic reactions with minimal loss in activity. In addition, new insights into the stabilization of nanoparticles in ionic liquids will be presented.
