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 + H-2 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, Au-197 Mossbauer characterizations and the activity measurements, although a small amount of Au-Pd alloy formed after the catalyst was calcined at 500 degrees C.
