| Abstract | Hierarchical Fe-ZSM-5 was synthesized with the aid of 3-glycidoxypropyltrimethoxysilane (GPTMS) and then was modified by the ammonia-steaming post treatment. Various techniques, such as XRD, SEM, N2 adsorption-desorption, UV-vis and NH3-TPD were used to characterize the as-obtained and modified hierarchical Fe-ZSM-5. The direct oxidation of benzene to phenol using N2O as the oxidizing agent was conducted on the ammonia-steaming treated Fe-ZSM-5. The results showed that compared to the steaming treated Fe-ZSM-5 catalysts, ammonia-steaming treated hierarchical Fe-ZSM-5 catalysts preserved more mediate strong acid sites and ex-framework iron active species, thus exhibited a higher catalytic activity in the catalytic oxidation of benzene to phenol with N2O, while the frame structure and pore structure of Fe-ZSM-5 was almost unchange. |
