Au/CeO₂catalysts 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/CeO₂catalysts exhibited high catalytic activity in water gas shift reaction supplied with oxygen, showing markedly enhanced catalytic activities due to highly dispersed Au particles over CeO₂with small crystallite size and large surface area.
