CO Oxidation over Bimetallic Au–Pd Supported on Ceria–Zirconia Catalysts: Effects of Oxidation Temperature and Au:Pd Molar Ratio
Au–Pd supported on ceria–zirconia catalysts, with Au:Pd molar ratios in the 1:1–10:1 range, have been prepared using deposition precipitation of Au followed by impregnation with Pd. The resulting Au–Pd supported catalysts were activated by oxidation at 350, 450 and 700 °C. The oxidation at 700 °C le...
