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20~30 nm，直径170~220 nm，在400~700 nm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。

Abstract: 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 170-220 nm and 20-30 nm, respectively. The Cu2O hollow micro-spheres exhibited strong absorption of light ranged from 400-700 nm and significant photodegradation effect on sewage.
Key words: Cu2O; hollow micro-spheres; photocatalysis; sewage
