Study by electrical conductivity measurement of redox properties of vanadium antimonate and mixed vanadium and iron antimonate
چکیده انگلیسی
Pure vanadium antimonate which was a n-type semiconductor, became p-type after reduction under propane. The change in type of electrical conductivity has been explained by a surface transformation with the formation of antimony oxide and a rutile-type solid solution with only cationic vacancies.xC3H8+V0.644+V0.283+Sb0.925+□0.16O4⇄(10.47x)V4+V0.28+2.18x3+Sb0.925+□0.16−0.5xO4+0.22xSb2O4The effect of vanadium substitution by iron on the electrical properties of the phase has been studied to understand the redox behavior of propane ammoxidation catalysts.
