摘要:

通过电纺丝法结合原位还原及原位氧化反应, 成功制备了均匀负载Ag/AgCl复合纳米粒子/聚丙烯腈(PAN)复合纳米纤维膜. 首先利用电纺丝技术制备了PAN/AgNO3复合纳米纤维, 然后用乙二醇将硝酸银还原成银纳米粒子, 最后采用三氯化铁溶液对材料进行原位氧化. 所得纤维膜材料可以作为高效的可见光催化剂, 具有高可见光利用率, 优异的柔性和高光催化动力学等特性.

Abstract:

Ag/AgCl composite nanoparticles/polyacrylonitrile nanofiber films were prepared by electrospinning and subsequent in-situ reduction combining in-situ oxidation strategy. Electrospinning was firstly used to fabricate PAN/AgNO3 composite nanofibers; then the AgNO3 was reduced by in-situ reduction with glycol; finally, an in-situ oxidation between Ag nanoparticles and FeCl3 solution was carried on to prepare the compo-site nanofiber films. The as-prepared materials can be used as high-performance photocatalysts, taking the advantage of the visible-light activity, flexibility, and high photocatalytic kinetics. The present method is helpful for the development of the high-performance membrane based photocatalysts.

Key words: Electrospinning, Ag/AgCl nanoparticle, Polyacrylonitrile nanofiber, Visible-light photocatalysis
