The iron-incorporated hexagonal mesoporous silica (HMS) material Fe-HMS was synthesized at ambient temperature by using dodecylamine as the template agent

and was characterized by XRD

BET，SEM

H2-TPR and N2 adsorption measurements.Its catalytic performance for oxidation of benzyl alcohol with H2O2 to benzyl aldehyde was investigated.The effects of reaction conditions were examined.The results showed that Fe3+ ions were incorporated into the framework of HMS

and Fe-HMS had a uniform mesoporous structure.Most of the Fe3+ ions (Fe2O3) of calcined Fe-HMS remained in the tetrahedral coordinated framework.Fe-HMS exhibited superior catalytic performance in the selective oxidation of benzyl alcohol compared to the common silica-supported material by the same method. At molar ratio of Si to Fe 25∶1

molar ratio of benzyl alcohol to H2O2 1∶2

catalyst content 4%(mass)

reaction time 85℃ and reaction time 4 h

the conversions of benzyl alcohol and the selectivity for benzyl aldehyde reached 65.1% and 74.6%

respectively.
