A simple microemulsion-based method has been developed to synthesize ZnCo(2)(C(2)O(4))(3) nanowires that can be transformed to porous ZnCo(2)O(4) nanowires under annealing conditions. The morphology of porous ZnCo(2)O(4) nanowires can be tuned by the initial ZnCo(2)(C(2)O(4))(3) nanowires and the annealing temperatures. The as-synthesized porous ZnCo(2)O(4) nanowires have been applied as anode materials of Li-ion batteries, which show superior capacity and cycling performance. The porous one-dimensional (1D) nanostructures and large surface area are responsible for the superior performance. Moreover, it is indicated that porous ZnCo(2)O(4) nanowires synthesized at low annealing temperature (500 °C) show larger capacity and better cycling performance than that prepared at high annealing temperature (700 °C), because of their higher porosity and larger surface area.
一种简单的基于微乳液的方法被开发用来合成 ZnCo(2)(C(2)O(4))(3)纳米线,这些纳米线在退火条件下可以转化为多孔 ZnCo(2)O(4)纳米线。多孔 ZnCo(2)O(4)纳米线的形态可以通过初始的 ZnCo(2)(C(2)O(4))(3)纳米线和退火温度来调节。所合成的多孔 ZnCo(2)O(4)纳米线已被用作锂离子电池的阳极材料,其表现出优异的容量和循环性能。多孔一维(1D)纳米结构和大的表面积是其优异性能的原因。此外,研究表明,在较低退火温度(500°C)下合成的多孔 ZnCo(2)O(4)纳米线比在较高退火温度(700°C)下制备的纳米线具有更大的容量和更好的循环性能,这是因为它们具有更高的孔隙率和更大的表面积。
