通过酸化模板法制备了掺杂有TiO2纳米粉体的聚吡咯纳米团簇,并通过光催化降解甲基橙以及橙II研究了其光催化性能。使用掺杂有TiO2的聚吡咯纳米团簇在紫外光照射条件下进行2 h光催化试验,甲基橙和橙II的降解率分别达到96%和98%。材料通过扫描电子显微镜、比表面分析、红外光谱、X射线衍射等手段表征。 The polypyrrole nanoclusters doped with TiO2 nanopowders were prepared by acid template method and their photocatalytic properties were studied by photocatalytic degradation of methyl orange and orange II. Photocatalytic degradation of methyl orange and orange II was 96% and 98%, respectively, using TiO2-doped polypyrrole nanoclusters under UV irradiation for 2 hours. Materials by scanning electron microscopy, surface area analysis, infrared spectroscopy, X-ray diffraction and other means.
