摘要: Three different Fe-Zr oxide systems were prepared using firstly classical impregnation of iron nitrates on calcined ZrO2 (Fex/ZrO2, x represents Fe/Zr ratio = 0.01 and 0.11), secondly dried zirconium hydroxide ZrO(OH)2 (Fex/ZrO(OH)2) finally hydrolysis aqueous suspension salts to coprecipitate hydroxides (Fex-Zr). Thermal decomposition study samples evidenced a delay in the temperature crystallization zirconia for Fex-Zr Fex/ZrO(OH)2, more content sample, important delay. For these samples, formation stabilization phases by several characterization techniques : X-Ray Diffraction (XRD), Raman spectroscopy Electron Paramagnetic Resonance (EPR).
