Abstract


The influence of conditions for V2O5-MoO3 catalysts hydrothermal treatment (HTT) by conventional and microwave heating on their physico-chemical and catalytic properties has been studied. The observed transformations have been investigated by XRD, FTIR, nitrogen adsorption, measurements of electroconductivity. The activity V-Mo-O samples in reaction of oxidative dehydrogenation of propane increases in row HTT-300°С > HTT-350°С > HTT-250°С according to changes of their conductivity G·10–5: 11 > 6 > 1 S/m.
