The Effect of Mechanochemical and Ultrasonic Treatments on the Properties of Composition CeO2–MoO3 = 1:1
The influence of mechanochemical (MChT) and ultrasonic (UST) treatment on the properties of CeO2–MoO3 = 1:1 composition was studied. It was shown that in both processes changes in crystalline, porous structures, and morphology occurred. It was found that MChT and UST of samples affect the characteristics of hydrogen temperature-programmed reduction (H2-TPR). The results of the catalytic activity of activated samples in an ethanol oxidation reaction demonstrate the high yield of acetic aldehyde (95%) at 230 °C and the productivity of this product (0.9 mol/kgcat · h).
