本文报道了在没有模板剂辅助的情况下，通过水热法合成了排列良好的CuO纳米片阵列。排列良好的CuO纳米片阵列的表面看起来像一堵墙。这些纳米片具有四个清晰的边缘，厚度为50-80 nm，宽度为150-250 nm，长度为0.8-1.5 μ m。电子显微镜检测表明纳米片晶沿[010]方向沿着生长。Ostwald熟化机制已被用来描述CuO纳米片的生长。此外，对所得产物的光学和电化学性质进行了讨论。CuO纳米片阵列在充放电过程中表现出紫外-可见光谱的蓝移、缓慢的容量衰减速率和较高的库仑效率。
This paper reports well-aligned arrays of CuO nanoplatelets synthesized through a hydrothermal route without template's assistance. The surface of well-aligned arrays of CuO nanoplatelets looks like a wall. These nanoplatelets, possessing four clear edges, are 50-80 nm in thickness, 150-250 nm in width, and 0.8-1.5 microm in length. Electron microscopic detection shows that the nanoplatelet grows along the [010] direction. The Ostwald ripening mechanism has been used to describe the growth of CuO nanoplatelets. In addition, the optic and electrochemical properties of as-obtained products have been discussed. And the arrays of CuO nanoplatelets exhibit the blue shift in UV-visible spectra, a slow capacity fading rate, and a relatively high Coulombic efficiency in charge-discharge process.
