The formation of Pd-carbide was observed in the CHF2Cl-treated catalyst, and the presence of the palladium carbide is thought to enhance the selectivity to the CH2F2 and to prevent sintering of palladium. XRD, TEM and XPS were used to characterize he structure and the composition of Pd/Al2O3. (C) 2000 Elsevier Science B.V. All rights reserved.
