Nanostructure Cu-Zn mixed-oxide (CZMO) have been prepared by an impregnation method using copper nitrate and zinc oxide tetrapod precursors. X-ray powder diffractometry (XRD) and field emission scanning electron microscopy (FESEM) were used to characterize the structural of CZMO. The XRD patterns confirmed metal oxides formation and their good crystallinity. In agreement with XRD results, FESEM images also illustrated nanosized particles with an average nanocrystallite size of 33 nm. The photocatalytic activity of CZMO was studied using the photocatalytic decolorization of C.I. Reactive Orange 16 (V3R) in aqueous environment. The results indicated that the CZMO display good photocatalytic efficiency. The related photocatalytic mechanism was discussed based on the coupling of zinc-copper oxide.
采用硝酸铜和氧化锌四脚前驱体通过浸渍法制备了纳米结构的铜锌混合氧化物(CZMO)。利用X射线粉末衍射仪(XRD)和场发射扫描电子显微镜(FESEM)对CZMO的结构进行了表征。XRD图谱证实了金属氧化物的形成及其良好的结晶度。与XRD结果一致,FESEM图像也显示出平均纳米微晶尺寸为33nm的纳米颗粒。通过在水环境中对C.I.活性橙16(V3R)进行光催化脱色研究了CZMO的光催化活性。结果表明,CZMO表现出良好的光催化效率。基于锌铜氧化物的耦合对相关的光催化机理进行了讨论。
