The key to improve the performance of heteroatom catalysts is to ensure the orderliness of catalysts and the good dispersion of heteroatoms. The alkalinity plays the indispensable role in synthetic process of V-MCM-41 catalyst. The excessive alkalinity of synthetic system will make the MCM-41 difficult to crystallize

even to dissolve. It is easy to accumulate for heteroatomic species in the system of low alkalinity. Herein

the highly ordered VMCM-41 with high vanadic content in framework is synthesized in the condition of excessive NH

O in this paper. A series of characterization results prove the good dispersion of vanadium species

and most of vanadium gets into the framework of MCM-41 with the states of tetravalence and pentavalence. Furthermore

the modified MCM-41 by other transition metals is successful synthesized by the method of V-MCM-41 in this paper. The VMCM-41 shows well catalytic activity for the selective oxidation of benzyl alcohol

which up to 74.83% for the conversion of benzyl alcohol and 96.20% for selectivity of benzaldehyde when initial V/Si=0.10. The paper provides the possibility f

or industrial application of V-MCM-41 in the oxidation of benzyl alcohol for benzaldehyde. Besides

the work provides a significant idea for the synthesis of modified MCM-41 by well-dispersed transition metals.
