Au catalysts supported on Al2O3 and MOx-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 FeOx. 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 AuIII, which resulted in different reaction mechanisms of preferential oxidation of CO in the presence of H2.
