模板法合成TiO_2掺杂的聚吡咯纳米团簇及其光催化性能研究
|
摘要
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。
Polypyrrole nano-clusters doped with TiO2 were prepared by acidize template method,and its photocatalysis property was investigated by photocatalytic degradation of methyl orange dye(MO) and orange II.The photocatalysis experiments were carried out under UV illumination for 2 h before an adsorption/desorption equilibrium.The degradation rates of MO and orange II was 96% and 98%.The nanoparticles morphology were characterized by SEM,ASAP and FTIR and XRD.
