Abstract 

Oxide mixture ZnO-MoO3 (1:1) was modified by mechanochemical (during 2, 4 and 8 hours in air) and sonochemical (1 hr in water solution) treatments. The properties of obtained samples were studied by means of XRD, IR-spectroscopy, BET, DTA-TG, SEM methods. It was shown, that both kinds of treatments lead to the change of oxides crystalline structure, their surface morphology, porous structure and decrease particle size. The formation β-ZnMoO4 in the milling process and β-Мо8О23 at ultrasonic effect it was found
