摘要

采用聚乙烯吡咯烷酮(PVP)作为模板聚合物、醋酸锆[(Zr(Ac)₄]为锆源、六水合硝酸钇[Y(NO₃)₃·6H₂O]为稳定剂,通过均质处理的方法在前驱体溶液中加入二氧化钛纳米颗粒(TiO₂-NPs)并利用静电纺丝技术及煅烧工艺制备了掺杂TiO₂-NPs的柔性钇稳定氧化锆(YSZ-TiO₂)纳米纤维膜,并研究了其对亚甲基蓝(MB)的降解效果。研究结果表明:在MB溶液浓度为10mg/L,降解时间为70min,TiO₂-NPs用量为8%条件下,制得的柔性YSZ-TiO₂纳米纤维膜对MB的降解率最高达到95%,有望应用在污水处理等领域。

Abstract

Poly(vinyl pyrrolidone)(PVP),zirconium acetate[Zr(Ac)₄],and yttrium nitrate hexahydrate[Y(NO₃)₃·6H₂O] were selected as polymer template,zirconium source and stabilizer,respectively.Additionally,TiO₂-NPs was introduced into precursor solution by homogenization treatment process.Finally,self-standing YSZ-TiO₂ nanofibrous photocatalyst membrane material were prepared for ultraviolet photocatalyst by a facile combination of electrospinning technique and calcination process,and the degradation effect of fiber membrane on methylene blue (MB) was studied.Among the various membranes,the YSZ-TiO₂ nanofibrous membranes with the 8wt% content of TiO₂-NPs showed the best UV photocatalytic performance for photocatalytic degradation of MB,which can up to 95% in 70min.It was expected to be used in sewage treatment and other fields.
