PURPOSE: Disclosed are a palladium catalyst supported on active carbon, a preparation method thereof and a hydrogenation reaction of chlorofluorocarbon to hydrofluorocarbon using the prepared catalyst. CONSTITUTION: The active carbon used as catalyst support is pretreated with a basic solution of 0.2-1M NaOH at 60-80deg.C for 1-5hours two or five times. And the acid treatment of a hydrochloric acid may be also conducted whenever after the base treatment or the hydrogen fluorine treatment or before loading of palladium species. The palladium species is impregnated by the adsorption precipitation method or the co-precipitation method. The hydrogenation reaction, dehalogenation, of chlorofluorocarbon to hydrofluorocarbon is selectively preformed to increase the yield of HFC-32.
