Abstract: The synthesis and the characterization of a novel vanadoaluminosilicate, V-MCM-22, with MWW structure, and of vanadyl-exchanged MCM-22 zeolite, [VO]-MCM-22, have been performed. V-MCM-22 was prepared using VOSO4 in the synthesis gel (H+ or Na+-exchanged samples were also prepared), while [VO]-MCM-22 was prepared by ion-exchange of MCM-22 with VO2+ ions. The materials were characterized by X-ray diffraction (XRD) and thermogravimetry (TGA). The presence of redox sites (V 4+/V5+ couples) was monitored by diffuse reflectance (DR) UV-Vis spectroscopy of oxidized (in O2 at 580°C) and reduced (in H2 at 500°C) samples. © 2005 Elsevier B.V.
