英文摘要	ti-zsm-5 samples were successfully synthesized by using b-zsm-5 with different molar ratios of (n)sio2/(n)b2o3 as the precursors. the gas-solid synthesis included two steps which were deboronation in hcl solution and titanation with ticl4. the effect of (n)sio2/(n)b2o3 on the incorporation of titanium into the framework was investigated. the synthesized titanium containing samples were thoroughly characterized by xrd, ft-ir, xrf, uv-vis, raman, icp-aes and nh3 tpd. propylene epoxidation and phenol hydroxylation properties were also investigated. the results showed that (n)sio2/(n)tio2 in the samples increased with an increase in the (n)sio2/(n)b2o3 in the precursors. the conversion of h2o2 increased with the decreasing of (n)sio2/(n)b2o3 or (n)sio2/(n)tio2, and the selectivity to propylene oxide (po) decreased. anatase appeared in ti-zsm-5 sample synthesized by using b-zsm-5 with a (n)sio2/(n)b2o3 ratio 100 as the precursor.
