阴离子树脂负载的ZnS固相光催化剂的制备及活性的研究

STUDY ON PREPARATION AND ACTIVITY OF ZnS/R SOLID-STATE PHOTOCATALYST LOADED BY ANION EXCHANGE RESIN

本文以Zn(NO3)2.6H2O为锌源,Na2S为硫源,采用强碱性阴离子交换树脂法制备了阴离子树脂负载的ZnS固相光催化剂,就Zn2+进入树脂孔道内形成ZnS纳米粒子进行了XRD表征,对影响光催化反应的pH、温度和催化剂的稳定性等因素进行了探讨,并以紫外灯为光源,以亚甲基蓝为模型污染物考察了该固相光催化剂的光催化活性。

ZnS/R Solid-state Photocatalyst was prepared by using Zn(NO3)2·6H2O as zinc source and Na2S as sulfur source through strong alkaline anion-exchange resin technology,XRD characterization suggests that Zn2+ have entered channels of the resin and formed into nanoparticles.Eeffect of pH value,temperature and stability of the catalyst on Photocatalytic reaction were discussed,Photocatalytic activity of the catalyst when taking ultraviolet as light source,methylene-blue as model pollutant were also investigated i...
