The influence of the ultrasonic treatment (UST) of the ZnO/MoO3 oxide system with atomic ratios of Zn/Mo = 15:85, 25:75, 50:50, and 75:25 on their properties was investigated. Using X-ray diffraction (XRD) analysis, it was found that in the sonochemical activation process, the phase transformation in molybdenum oxide, the formation of molybdenum suboxides (Mo4O11, Mo8O23), and the triclinic modification of the zinc molybdate α-ZnMoO4 occurred. The structure and morphology of ZnMoO4, which were characterized by transmission electron microscopy and scanning electron microscopy analyses, show the formation of nanodispersed needle-like crystals. It was found that as a result of sonochemical treatment, the grinding and increase in the specific surface area of the compositions take place. The samples obtained after UST demonstrate very promising results in the oxidative dehydrogenation of ethanol to acetaldehyde and the treated composition with a ratio of Zn/Mo = 50:50 permits an acetaldehyde yield equal to 94% to be obtained at a reaction temperature of 255 °C.
