Abstract: Using thermal and X-Ray diffraction analyses, effects of supported component loadings (V₂O₅ and NiO) on the processes of phase and structure formation in (0-25%)V₂O₅/γ-Al₂O₃, (0-25%)NiO/γ-Al₂O₃- and (0-10%)NiO-10% V₂O₅/γ-Al₂O₃ dehydrogenation catalysts during their preparation by impregnating commercial γ-Al₂O₃ (A-64, S = 200 m²/g) with aqueous solutions of NH₄VO₃ and Ni(NO₃)2·6H₂O, followed by drying (120°C, 4 h) and calcination (600°C, 6 h) of impregnates in air after each component deposition, have been investigated.
