Abstract

The effect of calcination temperature on the electronic structure of gold catalyst was investigated in this paper. CO oxidation was employed as a test reaction to correlate the phase changes to the catalytic activity. The TPR, XPS and XRD characterization showed that the highly active Au/FeO~x~/Al~2~O~3~ catalyst contained both gold atoms and ions. The catalytic performance of gold catalyst may depend on the Au^0^/Au^3+^ ratio. The best activity in the present work was obtained when the Au^0^/Au^3+^ ratio was about 0.89.
