高度有序的α-Fe(2)O(3)纳米管阵列通过简单且经济高效的铁箔阳极氧化方法制备而成。 α-Fe(2)O(3)纳米管阵列表现出高比电容（1.3 A.g(-1)时为138 F.g(-1)）、卓越的倍率性能（12.8 A.g(-1)时为91 F.g(-1)）和良好的循环稳定性（500次循环后电容保持率接近89%），这归因于α-Fe(2)O(3)纳米管独特的纳米结构阵列，提供高表面积、快速离子传输路径和坚固的结构。这些特性使得α-Fe(2)O(3)纳米管阵列电极对于超级电容器应用非常有吸引力。 (C) 2011 Elsevier B.V. 保留所有权利。
Highly ordered alpha-Fe(2)O(3) nanotube arrays have been fabricated by a simple and cost-effective anodization method on iron foils. The alpha-Fe(2)O(3) nanotube arrays exhibit high specific capacitance (138 F.g(-1) at 1.3 A.g(-1)), remarkable rate capability (91 F.g(-1) at 12.8 A.g(-1)) and good cycling stability (the capacitance retention close to 89% after 500 cycles), clue to the unique nanostructures of the alpha-Fe(2)O(3) nanotube arrays, which providing high surface area, fast ion transport pathways and robust structures. These features made the alpha-Fe(2)O(3) nanotube array electrode very attractive for supercapacitor applications. (C) 2011 Elsevier B.V. All rights reserved.
