摘　　要：以硝酸铜、乙酸铜、乙酰丙酮铜为原料,采用多元醇还原法合成制备了氧化亚铜立方体、微球、空心球、核壳结构等微纳米颗粒。利用X射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、高分辨透射电子显微镜(HRTEM)和紫外可见吸收光谱(UV-Vis)等测试手段对样品的物相、形貌、元素组分及吸光性能进行了表征。同时考察了铜源、反应时间、和多元醇类型对氧化亚铜微纳米材料形貌的影响,对产物形成机理进行了初步的探讨。对产物形成机理进行了初步的探讨。采用简单低廉的多元醇合成法,可以控制合成不同相貌的氧化亚铜微纳米结构。对制备形貌可控的氧化物具有一定的指导意义。Cu 2 O micro-and nanoparticles with different morphologies(cube,microsphere,hollow sphere and core-shell)were prepared by polyol method,using copper nitrate,copper acetate,and copper acetylacetonate as raw materials.The samples were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FE-SEM),transmission electron microscopy(TEM),high resolution TEM(HRTEM)and ultraviolet-visible(UV-Vis)spectroscopy.We investigated the influences of copper sources,reaction time,the polyol types and other conditions on the morphology of cuprous oxide.The mechanism for the formation of Cu 2 O in polyol process is discussed.Synthesis of cuprous oxide micro-and nanostructures with different shape can be controlled by the simple and inexpensive polyol method.This method is promising for the preparation of oxides with controlled morphologies.
