Textural Characteristics and Structural Peculiarities of Supported Vanadium Oxide Materials Prepared by the NH_4VO_3 Aqueous Solution Wetness Impregnation

摘要

Textural characteristics and structural peculiarities of materials based on supported vanadium oxide are considered. The materials were prepared by the incipient wetness impregnation of SiO_2, TiO_2, γ-Al_2O_3 and carbon-modified γ-Al_2O_3 supports using an aqueous solution of NH_4VO_3. Samples were characterized by low temperature N_2 adsorption, XRD, IR, Raman and US-Vis DR spectroscopy and H_2-TPR.
