A novel Au&Pd/Fe(OH)x catalyst with separate Au and Pd active sites was designed and synthesized. It was found for the first time that total conversion of CO + H2 could be achieved at room temperature over this catalyst. The separate Au and Pd sites in Au&Pd/Fe(OH)x catalyst were confirmed by the XPS, XRD, 197Au MÖssbauer characterizations and the activity measurements, although a small amount of Au–Pd alloy formed after the catalyst was calcined at 500 ℃.
