| 摘 要： | 采用静电纺丝法,以聚乙烯醇(PVA)和硝酸镍(Ni(NO3)2)为前驱物,制得PVA/Ni(NO3)2纤维;再以尿素(CO(NH)2)为碱源,通过水热合成法制备了PVA/NiO复合纳米纤维.利用X射线衍射(XRD)、红外光谱(FT-IR)、扫描电镜(SEM)和透射电子显微镜(TEM)等分析测试手段对样品的形貌和结构进行了表征,以罗丹明B为目标降解物,考察了PVA/NiO复合纳米纤维的光催化活性.结果表明:NiO纳米粒子均匀地负载于PVA纳米纤维上,形成了具有良好光催化活性的PVA/NiO复合纳米纤维光催化材料.

| Abstract: | Polyacrylic nitrile(PVA)/nickel nitrate(Ni(NO3)2) composite nanofibers were firstly fabricated through electrospinning a precursor solution of PVA and Ni(NO3)2.After further urea assisted hydrothermal treatment,PVA/NiO composite nanofibers were obtained.The morphology and structure of the product were characterized by XRD,FT-IR,SEM and TEM.The results showed that NiO nanoparticles could be evenly grown on the surface of PVA nanofibers.By employing degradation of rodamine B as model reaction,it was found that as-fabricated PVA/NiO composite nanofibers possessed good photocatalytic activity. |
