摘要：

采用温和的水溶液法，以CuCl2·2H2O和H2C2O4·2H2O为原料合成了新颖结构CuC2O4多孔球。产物的结构与形貌用X射线衍射（XRD）, 扫描电子显微镜（SEM）表征。研究了不同实验条件如反应温度、反应物浓度、不同体积阴离子等对产物形貌与尺寸的影响。结果表明，单斜结构的CuC2O4多孔球直径约400~540 nm，每个多孔球由尺寸约为50~80 nm的纳米粒子自组装而成。反应物浓度及阴离子体积能调节纳米粒子的团聚尺寸，而反应温度可有效调节多孔球的尺寸。刻蚀过程解释了CuC2O4多孔球的形成机理。

Abstract:

Novel CuC2O4 porous spheres were prepared on a large scale by a mild aqueous solution method at 100 ?C for 10 h using CuCl2 and H2C2O4 as raw materials. Structure and morphology of as-products were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The influence of experimental conditions such as concentration of reactants, reactive temperature and the volume of anions on the structure and morphology of as-products have been carried out. The results showed that as-products were monoclinic structure CuC2O4 porous spheres with diameter of 400-540 nm. Each porous sphere is made of many nanoparticles with size of 50-80 nm. Reactant temperature has more effect on the size of the CuC2O4 porous spheres, and concentration of reactants and cupric salts have all influence on the size of aggregates of particles. So through adjusting the experimental conditions, CuC2O4 porous spheres could be controlled-synthesis. The formation mechanism of CuC2O4 porous spheres based on the etching effect was discussed.
