Ceria-Supported Bimetallic Catalysts for the Oxygen-Assisted Water-Gas-Shift Reaction for Hydrogen Production

摘要

The oxygen-assisted water-gas-shift (OWGS) reaction is an effective process concept for more efficient conversion of CO at low temperature. Ceria-supported Cu-Pd bimetallic catalyst is a very promising catalyst for OWGS. The oxygen transfer properties of CeO_2 play an important role aiding the oxidation of carbon monoxide with oxygen-assisted water-gas-shift reaction over the Cu-Pd based catalysts. It can also be inferred that Pd plays an important role in aiding the reaction and/or stabilizing the catalyst.
