The catalytic properties of the systems based on the nanosize copper and zinc oxides fabricated by means of different methods are investigated during methanol decomposition and selective CO oxidation. The activity dependence of catalysts on the preparation method is established. Higher activity of the samples prepared by mechanical mixing pre-formed monodisperse copper-oxide nanoparticles (average size of 12 nm) with magnesium oxide in comparison with copper-based systems after mechanochemical treatment and prepared by impregnation method is found. The stabilization role of the zinc oxide in the copper-containing catalysts is shown.
