Preparation of palladium on carbon for hydrogenation catalyst using [Bmim][CF₃SO₃] as an effective solvent

Palladium particles were synthesized with 1-buthyl-3-methylimidazolium trifluoromethanesulfonate ([Bmim][CF₃SO₃]) as an effective solvent during the synthesis. The morphology of the particles was affected by the concentration of [Bmim][CF₃SO₃]. Furthermore, the palladium on carbon powder was prepared with various [Bmim][CF₃SO₃] concentrations and calcinations temperatures as a catalyst for hexafluoropropylene hydrogenation. Catalytic activity was varied by both conditions significantly. Under the identical condition, the catalyst prepared by the same mole ratio of [Bmim][CF₃SO₃] and palladium, and calcined at 500 °C was the most active in this reaction.
