摘　　要：With B-ZSM-5 zeolite from modified hydrothermal synthesis as precursor,Ti-ZSM-5 samples were synthesized under different gas-solid reaction temperature.The samples were characterized with TG,XRD,XRF,FT-IR,UV-Vis and so on.The phenol hydroxylation properties of Ti-ZSM-5 were also investigated.The results show that,the gas-solid reaction temperature affects the type and amount of titanium in Ti-ZSM-5.Ti-ZSM-5 samples from gas-solid synthesis with the gas-solid reaction temperature from 423 K to 873 K show similar properties in phenol hydroxylation.The effect of extra-framework titanium on phenol hydroxylation properties is neglectable.With B-ZSM-5 zeolite from modified hydrothermal synthesis as precursor, Ti-ZSM-5 samples were synthesized under different gas-solid reaction temperature.
