摘要：
A galvanostatic anodization is used to prepare long TiO2 nanotube arrays (TNTAs). TNTAs of over 100 mu m in length, with similar nanotube size and structural regularity to the classic TNTAs made from potentiostatic mode, are achieved at 10 mA cm(-2). After a post-anodization in a H3PO4-based electrolyte, the TNTAs with long nanotubes exhibit good adhesion to Ti substrate. The as-prepared long TNTAs yield a larger areal capacitance of 128.4 mF cm(-2). Further, the long TNTAs possess a higher surface area, making them suitable as support templates for other active materials. (C) 2016 Elsevier B.V. All rights reserved.
