EFFECT OF THE NATURE OF THE SUPPORT FOR COPPER–CERIUM OXIDE CATALYSTS ON SELECTIVE OXIDATION OF CO IN HYDROGEN-RICH MIXTURES

We have studied the catalytic properties of copper–cerium oxide catalysts, supported on zirconium, aluminum, titanium, and manganese oxides, in the reaction of selective oxidation of CO in hydrogen-rich mixtures. We have shown that the high activity and selectivity of catalysts supported on zirconium and aluminum oxides is connected with the presence of (in addition to divalent copper) higher amounts of copper in the (+1) oxidation state in the catalysts.
