| Summary: | HZSM-5 supported SrTiO<sub>3</sub> was prepared using sol-gel method. The materials were characterized by XRD, SEM, BET, BJH and FT-IR measurements. The activity of photocatalytic degradation of reactive brilliant red X-3B was studied on SrTiO<sub>3</sub>/HZSM-5. The results show that SrTiO<sub>3</sub> material is mainly composed of perovskite SrTiO<sub>3</sub>, as well as a small amount of SrCO<sub>3</sub> phase. SrTiO<sub>3</sub> is coated on the external surface of HZSM-5 in the <i>χ</i>SrTiO<sub>3</sub>/HZSM-5. The specific surface area of the supported materials is mainly provided by the zeolite, while pore size in the materials is mainly in the range between 2-20nm. Photocatalytic activity of SrTiO<sub>3</sub> is obviously enhanced after being supported, and the 30%SrTiO<sub>3</sub>/HZSM-5 has the maximum activity. 93.8% of reactive brilliant red X-3B can be degraded on 30%SrTiO<sub>3</sub>/HZSM-5 after 90 minites irradiation, while only 23.9% of the dye can be degraded on pure SrTiO<sub>3</sub>. |
