摘要: Mechanochemical activation of individual V2O5, MoO3 and mixed vanadium-molybdenum oxide system in various media (air, water, ethanol) has been studied. Powder X-ray diffraction, nitrogen adsorption–desorption, thermogravimetric chemical analysis, FTIR Raman spectroscopy, scanning electron microscopy have used for research prepared milled samples. The electrokinetic properties (dependence zeta potential—pH, position isoelectric point) vanadium–molybdenum system, synthesized via mechanochemical treatment medium, aqueous solutions electrolytes also determined. Initial, milled, spent samples are characterized with the help XRD, SEM adsorption nitrogen. catalytic composition activated different investigated reaction oxidation dehydrogenation propane.
