The use of CCl 4 as an effective medium to generate important phase changes in supported Pd and Au catalysts is presented. The dissolution of carbon that originates from CCl 4 to form a PdC 0.13 solid solution is more complete for the lowest temperature of the CCl 4 +H 2 reaction (30–50 °C). At higher temperatures, the bulk carbiding competes with the hydrogenative removal of bare carbon species to contribute to an enhanced CH 4 and C 2 H 6 formation.
