Abstract

Provided is a palladium on carbon (Pd/C) catalyst obtained by using an ionic liquid, a method for preparing the same, and a method for hydrogenation of hydrofluorocarbon using the same. More particularly, palladium particles are supported on carbon particles by using an ionic liquid, and the resultant Pd/C catalyst is used for hydrogenation of hydrofluorocarbon. The catalyst includes palladium particles having a smaller particle size and a more uniform shape as compared to the existing Pd/C catalysts, and thus shows high catalytic activity.
