(1-10wt.%) CuO-Gd0.1Ti0.1Zr0.1Ce0.7O2 mesoporous catalysts were prepared by simple coprecipitationmethod with sonication and tested for CO oxidation. The catalysts show the highest activity dueto better dispersion of CuO species as well as enhanced interaction between CuO and the developed support. Itwas shown that these systems have full conversion at temperature of 60–65◦C.
