Abstract
Spherical V-MCM-48 was synthesized by one-step hydrothermal method under low template concentration using ethanol as the co-solvent. The materials were characterized by XRD, FS-SEM, N 2 adsorption, FTIR, Raman, NMR, XPS and ICP. The results show that the materials are with high specific surface area (1005 m 2.g -1), ordered malodorous structure and spherical morphology. V 2O 5 crystal is not found when the V/Si molar ratio is 2.91%. Most of vanadium is incorporated to the framework of silica. The materials are effective catalysts in the oxidation of the styrene with H 2O 2 under low temperature.
