Effects of Diameters on the Catalytic Activity of Spherical V-MCM-41 in the Selective Oxidation of Styrene

摘要：

　　Spherical V-MCM-41s with different diameter are synthesized by direct hydrothermal method through the precise control over the molar ratio of NaOH/TEOS.Vanadium supported on spherical MCM-41s is also prepared by impregnation methods.They are used as heterogeneous catalysts for the oxidation of styrene with H2O2 as oxidant.The results suggest that all catalysts have high catalytic activity,which increases with their diameter decreasing.
