Development of Au/CeO2 Catalyst for Water Gas Shift Reaction Supplied with Oxygen
Au/CeO2 catalysts were prepared by deposition-precipitation and appled for water gas shift reaction supplied with oxygen in the presence of excess hydrogen and carbon dioxide. The catalysts were characterized by means of XRD, H2-TPR, CO chemisorption and XPS. The Au/CeO2 catalysts exhibited high catalytic activity in water gas shift reaction supplied with oxygen, showing markedly enhanced catalytic activities due to highly dispersed Au particles over CeO2 with small crystallite size and large surface area.
