摘要
以硫酸铜为铜源,聚乙烯吡咯烷酮(PVP)为表面修饰剂,水合肼为还原剂,在水溶液中制备纳米氧化亚铜颗粒构成的空心微球。通过扫描电子显微镜、透射电子显微镜、X射线衍射、紫外-可见光漫反射光谱等手段对样品进行表征,并研究了氧化亚铜空心微球对生活污水的光催化降解性能。研究结果表明,氧化亚铜空心微球壳厚20～30nm,直径170～220nm,在400～700nm波长范围有较强吸收,对生活污水有明显的光催化降解效果。
Hollow micro-spheres composed of Cu2O nano-particles were synthesized in aqueous solution with CuSO4 as copper source,PVP as surface modifier and N2H4.H2O as reductant.The sample was characterized with SEM,TEM,XRD,and UV-vis.The photocatalysis of Cu2O hollow micro-spheres on sewage was also investigated.The results indicated that the diameter and thickness of the hollow micro-spheres were 170220nm and 20-30nm,respectively.The Cu2O hollow micro-spheres exhibited strong absorption of light ranged from 400-700nm and significant photodegradation effect on sewage.
