Abstract

The vanadium-incorporated molecular sieve VAPO-5 was synthesized hydrothermally and characterized by X-ray diffraction, electron paramagnetic resonance, thermogravimetric analysis, diffuse reflectance spectroscopy, chemical analysis and adsorption techniques. It seems that the vanadium is incorporated mainly as V⁴⁺ in the as-synthesized VAPO-5 framework. The vanadium in VAPO-5 exists in a well dispersed state and shows redox properties, changing its oxidation state readily between V⁴⁺ and V⁵⁺.
