Influence of V Content on the Nature and Strength of Acidic Sites in VSiβ Zeolite Evidenced by IR Spectroscopy

VSiβ zeolites prepared by a two-step postsynthesis method have been characterized by physical techniques. A significant reduction of intensity of the IR band near 3515 cm-1 after impregnation of dealuminated β zeolite with aqueous NH4VO3 indicates that V ions specifically react with hydrogen-bonded...
