Sodium citrate (8.07 g) was dissolved in 807 ml of water, to which was added 56 ml of 6.7×10-3M PdCl2. This mixture was further diluted with 403 ml of water. The mixture was heated to boiling for 10 hours to form a Pd-sodium citrate colloid solution. To this was added 2 g fluorinated carbon (fluorine content 28%, median particle size less than one micrometer, surface area 130 m2 /g) together with 100 ml methanol. The solution was evaporated and the solid was reduced in hydrogen for 14 hours at 300° C. The resultant catalyst contained approximately 0.7% Pd. The catalyst was a partially wettable, black, slightly sticky powder.
