Abstract: The Ni₂V₂O₇ was prepared by sol-gel method using citric acid as complexing agent and characterized by X-ray diffraction, nitrogen physisorption, inductively-coupled plasma atomic emission spectroscopy, hydrogen temperature-programmed reduction, X-ray photoelectron spectroscopy and transmission electron microscopy. The temperature of the xerogel decomposition into Ni₂V₂O₇ and the thermal effects of decomposition process were investigated by DTA-TGA. The relationship between calcination temperatures and the formation of Ni₂V₂O₇, as well as the influence of calcining temperatures on the catalytic performance for the oxidative dehydrogenation of propane to propene were studied.

Key words: Ni₂V₂O₇; Sol-Gel method; Propane; Oxidative Dehydrogenation
