Fabrication of Through-hole TiO2 Nanotube Arrays by Bilayer Ti Foils Anodization DING Zhengnan, KONG Zhijian, Huayan LIU, CHEN Yinfei and ZHANG Zekai1,a 1 College of Chemical Engineering, Zhejiang University of Technology, Chaowang road 18, 310014 Hangzhou, China azzk@zjut.edu.cn Keywords: TiO2; nanotube; open-ended; anodization Abstract.
Then potential shock method, i.e., exerting an abrupt increase in the potential at the end of the anodization, has been investigated by many researchers. [9-12] Luo et al [13] proposes a mechanism that the fluoride-rich layer between Ti substrate and nanotubes is the key factor to fabricate through-hole TiO2 nanotube arrays.
