The influence of mechanochemical (MChT) and ultrasonic (UST) treatment on physic-chemical properties of СеО2-МоО3=1:1 composition was studied. The prepared samples were characterized by methods of XRD, ESR, N2 adsorption, SEM and TEM methods. The catalytic properties of obtained samples were studied in selective ethanol oxidation reaction. It was established the increase of specific surface area, decrease crystallites size and nanostructures formation of type “core-shell” due to MCh and US treatment. The change of physico-chemical properties of the compositions as a result of their mechano- and sonochemical treatment leads to increase their catalytic properties. The samples obtained after MCh and US treatments demonstrate very promising results in oxidative dehydrogenation of ethanol to acetaldehyde and the treated compositions permit to obtain the acetaldehyde selectivity equal 97 % at reaction temperature about 200ºC. It was shown that mechno- and sonochemical treatments of oxide mixture allow to obtain a high acetic aldehyde yield (97%) at 215°C and productivity on this product 1.8 mol/kg·h.
