Highly Conducting Spaced TiO Nanotubes Enable Defined Conformal Coating with Nanocrystalline NbO and High Performance Supercapacitor Applications
Selda Ozkan, Nhat Truong Nguyen, Imgon Hwang +2
In this work, we report on the electrochemical behavior of nitrided spaced TiO nanotubes conformally coated with a nanocrystalline NbO layer and find for these hierarch…
TiO nanotubes with different spacing, FeO decoration and their evaluation for Li-ion battery application
Selda Ozkan, Gihoon Cha, Anca Mazare +1
In present work, we report on the use of organized TiO nanotube layers with a regular intertube spacing for the growth of highly defined -FeO nano-needles in the int…
TiO2 nanotubes with laterally spaced ordering enable optimized hierarchical structures with significantly enhanced photocatalytic H2 generation
Nhat Truong Nguyen, Selda Ozkan, Imgon Hwang +2
In the present work we grow self-organized TiO2 nanotube arrays with a defined and controlled regular spacing between individual nanotubes. These defined intertube gaps allow to bu…
Transparent TiO2 Nanotubes Arrays Directly Grown on Quartz Glass Used in Front- and Back-Side Irradiation Configuration for Photocatalytic H2 Generation
JeongEun Yoo, Marco Altomare, Mohamed Mokhtar +4
In the present work we explore the front- and back-side performance of a photocatalytic platform consisting of self-organized TiO2 nanotube layers formed by complete anodization of…
Photocatalytic H2 generation using dewetted Pt-decorated TiO2 nanotubes - Optimized dewetting and oxide crystallization by a multiple annealing process
JeongEun Yoo, Marco Altomare, Mohamed Mokhtar +4
In the present work we use TiO2 nanotube arrays, carrying a Pt coating that is optimally dewetted, as a photocatalyst to generate H2. In order to achieve a maximum H2-generation ef…
