Catalytic activity of CuO-Gd0.1Ti0.1Zr0.1Ce0.7O2 in CO oxidation

(1-10wt.%) CuO-Gd 0.1 Ti 0.1 Zr 0.1 Ce 0.7 O 2 mesoporous catalysts were prepared by simple co-precipitation method with sonication and tested for CO oxidation. The catalysts show the highest activity due to better dispersion of CuO species as well as enhanced interaction between CuO and the develop...

Summary:(1-10wt.%) CuO-Gd 0.1 Ti 0.1 Zr 0.1 Ce 0.7 O 2 mesoporous catalysts were prepared by simple co-precipitation method with sonication and tested for CO oxidation. The catalysts show the highest activity due to better dispersion of CuO species as well as enhanced interaction between CuO and the developed support. It was shown that these systems have full conversion at temperature of 60–65 ∘ C. Graphical Abstract (1-10wt.%) CuO-Gd 0.1 Ti 0.1 Zr 0.1 Ce 0.7 O 2 mesoporous catalysts show the highest activity of CO oxidation (full conversion at temperature of 60-65°C) due to better dispersion of CuO particles and enhanced interaction between CuO and the developed support based on ceria solid solution.
