以CuC_2O_4微球为模板可控合成一维CuC_2O_4/ZnO异质结构(英文)

Controlled-Synthesis of CuC_2O_4 /ZnO Heterostructures Using CuC_2O_4 Microspheres as Templates

以CuC2O4纳米微球为模板,通过水热法在120℃、1 h时成功合成了一维CuC2O4/ZnO异质结构。采用热重分析(TGA)、场发射扫描电子显微镜(FE-SEM)、能量散射X射线谱(EDX)、透射电子显微镜(TEM)和X射线粉末衍射(XRD)等测试技术对产物的结构和形貌进行了表征。结果表明,所得产物为一维CuC2O4/ZnO纳米棒束,长约1μm,直径约500 nm。每个棒束由许多纳米棒沿同一方向组装而成。TEM照片和EDX光谱表明,CuC2O4和ZnO形成了均匀的异质结构。

One-dimensional CuC2O4/ZnO heterostructures were successfully prepared via hydrothermal reaction for 10 h at 120 ℃ using CuC2O4 microspheres as templates. Thermal gravimetric analysis （TGA）, field-emission scanning electron microscope（FESEM）, energy dispersive X-ray spectrometry（ EDX）, transmission scanning electron microscope（TEM） and powder X-ray diffraction （XRD） were used to characterize the structure and morphology of the products. Results show that the obtained products are CuC20JZnO nanorod bundles with 500 nm in diameter and 1μm in length. Each rod bundle consists of many nanorods which grow along the same orientation. TEM image and EDX spectra show that the product is a uniformly heterostructured material formed from CuC2O4 and ZnO.
