摘要
介绍了SrTiO3膜降解维多利亚蓝染料的光催化活性,同时也与商业P-25进行了比较,对PH的影响、合成温度和合成钙钛矿中Sr/Ti比例进行了比较。另外,Ag掺杂SrTiO3显示出最高的催化活性。在紫外-可见光下降解染料只有Ag-SrTiO3的光催化活性增强。
The photocatalytic activity of strontium titanate （SrTiOa） perovskite films has been examined and compared with that of commercially available titania （TiO2, Degussa P25） in the degradation of a model pollutant, Victoria Blue dye, The effects of pH, synthesis temperature, and Sr/Ti ratio in the synthesis of the perovskite were examined. Addition of Ag to SrTiO3 showed the most promising catalytic activity toward dye degradation. Degradation of the dye under UV-visible light was also observed to be enhanced only for Ag-SrTiOa.
