mechanochemistry

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

Oxide system CeO2-MoO3 with atomic ratio Ce/Mo = 15:85, 25:75, 50:50 and 75:25 was modified by mechanochemical treatment (MChT) during 2, 4 and 8 hours in air. Obtained samples were studied by means of XRD, BET, ТЕМ, sorption from the solution methods. It was shown, that mechanochemical modification leads to change of oxides crystalline structure, their surface morphology, porous structure and sorption ability to safranin-T dye.
