摘要:
Highly ordered &alpha;-Fe<inf>2</inf>O<inf>3</inf> nanotube arrays have been fabricated by a simple and cost-effective anodization method on iron foils. The &alpha;-Fe<inf>2</inf>O<inf>3</inf> nanotube arrays exhibit high specific capacitance (138 F&bullg<sup>- 1</sup> at 1.3 A&bullg<sup>- 1</sup>), remarkable rate capability (91 F&bullg<sup>- 1</sup> at 12.8 A&bullg <sup>- 1</sup>) and good cycling stability (the capacitance retention close to 89% after 500 cycles), due to the unique nanostructures of the &alpha;-Fe <inf>2</inf>O<inf>3</inf> nanotube arrays, which providing high surface area, fast ion transport pathways and robust structures. These features made the &alpha;-Fe<inf>2</inf>O<inf>3</inf> nanotube array electrode very attractive for supercapacitor applications. &copy;2011 Elsevier B.V. All Rights Reserved.
