Abstract

V-MCM-41s with high content of vanadium have been synthesized using sol-gel method under ammonium condition and characterized by using XRD, N₂ adsorption isotherms, HRTEM, ICP and Laser Raman Spectroscopy (LRS) techniques. Regular mesopore structure could be maintained up to the V/Si molar ratio of 0.14, although certain amount of V₂O₅ crystals becomes to disperse on the wall of MCM-41 when n_V/n_Si exceeds 0.11. These materials were effective catalysts in the hydroxylation of benzene with H₂O₂ under room temperature.
