采用表面活性剂(CTAB)调制的方法成功制备尖晶石型ZnCo2 O4纳米颗粒,利用 X射线衍射仪(XRD)、扫描电子显微镜镜(SEM)、透射电子显微镜(TEM)以及紫外-可见(UV-Vis)分光光度计对采用CTAB调制与未采用 CTAB 调制制备的 ZnCo2 O4颗粒的结构、形貌以及催化降解性能进行了对比分析.结果表明,制备出的 ZnCo2 O4纳米颗粒平均粒径为15.6 nm,对刚果红可见光催化降解具有很好的光催化活性,降解效率高.

The spinel zinc cobaltite nanoparticles were prepared via using a surfactant-mediated method.The structure,morphologies and catalyzed degradation of the as-synthesized products were characterized by X-Ray powder diffraction (XRD),scanning electron microscope (SEM),transmission electron microscope (TEM), and spectrophotometer,respectively.The results indicate that the as-prepared ZnCo2 O4 powders are nanocrys-tallines with the spinel structure and consist of crystalline particles of 1 5 .6 nm,which are weakly aggregated.It was found that ZnCo2 O4 nanoparticles have a good catalyzed degradation property for organic pollutants congo red (CR)from wastewater.
