Synthesis of Polypyrrole Nanoparticles by Microemulsion Polymerization and its Photocatalytic Application

通过W/O微乳法制备了聚苯胺纳米颗粒,研究其光催化降解有机染料甲基橙与橙Ⅱ的性能。通过在UV和UV/H2O2体系中的光催化降解实验发现,针对两种染料,聚苯胺纳米颗粒的光催化活性分别为普通聚苯胺的2.69倍与2.26倍。材料通过透射电子显微镜、比表面分析、红外光谱等手段表征。结合微乳法制备共轭聚合物材料,有可能为光催化降解有机污染物提供一条可行途径。

Polyaniline nanoparticles prepared by W/O microemulsion method are found to be photocatalytically active for degradation of methyl Orange dye(MO) and Orange II.During the photodegradation of Orange Ⅱ and Methyl Orange as organic dyes in UV/H2O2 and UV irradiation systems using Polyaniline nanoparticles as photocatalyst,it exhibits significant photocatalytic activity to double dyes in UV and UV/H2O2 system.The spherical polymer nanoparticles is characterized by TEM,ASAP and FTIR spectroscopies.Preparation of conjugaterd polymer by microemulsion may offer a feasible way for the photocatalysis degradation of organic pollutants.
