A three-piece suite: The immobilization of a Pd-nanoparticle catalyst onto the surface of a molecular sieve by an ionic liquid (1,1,3,3-tetramethylguanidinium lactate) has been accomplished (see TEM image). The nanoparticle/ionic liquid/molecular sieve combination exhibits excellent synergistic effects that enhance the activity and durability of the catalyst for the hydrogenation of olefins.
