Au catalysts supported on Al₂O₃ and MO_x-Al₂O₃ (M=Fe and Zn) were prepared by the deposition-precipitation method. Their catalytic activities for CO oxidation in the absence and presence of an H₂-rich steam at room temperature were investigated in detail. Catalyst bed temperatures were determined directly by a thermocouple. The catalyst surface temperature depended on the volume ratio of O₂/CO, and the concentrations of CO and H₂. The temperature on the Au/Al₂O₃ surface can reach 170°C during CO oxidation, and is decreased to 55°C by addition of FeO_x. These results indicate that formation of hot-spots on γ-alumina-supported ld catalysts could be controlled by adding an appropriate dopant. The structure of the catalysts was characterized by techniques such as X-ray powder diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy. Addition of a dopant could transfer the active center from Au to Au^III, which resulted in different reaction mechanisms of preferential oxidation of CO in the presence of H₂.
