Abstract
Rational design and processing are critical to the fabrication of high performance architectures. Although the fabrication of titania nanotube (TN) array films has been studied extensively during the last decade, fabrication of ordered nanoporous titania structures at ambient conditions still remains a challenge. In this work, we report a method for the fabrication of hybrid TN/nanopore layers by altering the electrochemical conditions during titanium anodization. The electrochemical and photocatalytic properties of nanolayers at different stages of the transition from nanoporous TiO2 to nanotubular TiO2 structure were studied by different electrochemical characterization techniques.
