| Notes | 11-1800/TB strontium titanate; photocatalysis; HZSM-5; sol-gel HZSM-5 supported SrTiO3 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-3Bwas studied on SrTiO3/HZSM-5.The results show that SrTiO3 material is mainly composed of perovskite SrTiO3,as well as a small amount of SrCO3 phase.SrTiO3is coated on the external surface of HZSM-5in theχSrTiO3/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 2-20 nm.Photocatalytic activity of SrTiO3 is obviously enhanced after being supported,and the 30%SrTiO3/HZSM-5has the maximum activity.93.8% of reactive brilliant red X-3B can be degraded on 30%SrTiO3/HZSM-5after 90 minites irradiation,while only 23.9%of the dye can be degraded on pure SrTiO3.
