采用软化学法，以氯化铜（CuCl2·2H2O）、氢氧化钠（NaOH）、聚乙烯吡咯烷酮（PVP）、抗坏血酸（C6H8O6）等为原料，制备了单分散、粒径可控的不同形貌纳米晶氧化亚铜。探讨了不同PVP加入量对氧化亚铜形貌的影响，并通过XRD、SEM、FT‐IR等对最终产物的粒径、形貌进行了表征，同时还测试了不同形貌样品对甲基橙（MeO）的吸附性能。结果表明：通过此方法制备出的晶体为纯相氧化亚铜，结晶性能好，纯度高；产物的分散性好，颗粒尺寸分布均一；PVP的加入量对氧化亚铜形貌有着重要影响，当R（R为PVP与CuCl2·2H2O的物质的量摩尔比）值为0、10、30时，制备的纳米晶氧化亚铜形貌分别为立方体、十四面体和八面体，且平均粒径为900nm；吸附性能测试表明制备的八面体氧化亚铜具有很强的吸附性能。
