The utilization of precious-metal promoted ceria for the catalysis of the water-gas shift reaction has prompted a need for more efficient and economical use of the precious metal promoter. It has been demonstrated that utilizing a volatile, organometallic precursor and a gas-phase incorporation method yields greater activity for the water-gas shift reaction when directly compared to conventionally prepared palladium-promoted ceria catalysts. Catalysts containing 1 - 5% Pd, derived from the gas-phase incorporation of (cyclopentadienyl)(allyl)palladium on ceria, yielded as much as 150% greater activity in comparison to conventional catalysts. Improvements in activity are due to greater dispersion of the palladium deposited from the gas phase.
