Palladium on carbon catalysts for hexafluoropropylene hydrogenation were prepared using imidazolium hexafluorophosphate with various cation parts. The morphology of palladium was relatively affected by the cation parts of the ionic liquid. With increasing alkyl chains of the ionic liquid cation, the shape of palladium particle changed from spherical to cylindrical due to the effect of steric stabilization. After calcination at 500 °C, all catalysts possessed the comparable crystal structure. Under the identical reaction conditions, the catalyst prepared using the ionic liquid with hexyl chain in cation parts showed the most effective reactivity.
