Abstract
Sodium silicate was used as the silica sour ce, CTMABr and TMAOH w ere used as template and mineralizer respectively. The pH value of the mixture w as adjusted with HCl(12 mol*L-1) Fe-MCM-41 were successfully synthesized in mild hydrothermal system at 75 ℃ for 16 h. The product was characterized by p owde r X-ray diffraction (XRD), N2 adsorption/desorption and FTIR. XRD, N2 adsor ptio n and FTIR show that the solid sample has an excellent crystalline structure and a typical mesopores characterization.Fe-MCM-41 was used as the heterogeneous catalyst for the oxidation of benze ne b y using H2O2 as the oxidant.The influences of solvent ,reaction time and cat alys t content were investigated. The liquid product was analyzed by a gas chromatogr aph. The result show that Fe-MCM-41 can efficiently catalyze the oxidation of benzene, and phenol is the only product of liquid phase.关键词
