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…
Hierarchical DSSC structures based on single walled TiO2 nanotube arrays reach back-side illumination solar light conversion efficiency of 8%
Seulgi So, Imgon Hwang, Patrik Schmuki
In the present work we introduce a path to the controlled construction of DSSCs based on hierarchically structured single walled, self-organized TiO2 layers. In a first step we des…
Single-walled TiO2 Nanotubes: Enhanced Carrier-transport Properties by TiCl4-Treatment
Imgon Hwang, Seulgi So, Mohamed Mokhtar +4
In the present work we report significant enhancement of the photoelectrochemical properties of self-organized TiO2 nanotubes by a combined de-coring of classic nanotubes followed…
Tantalum nitride nanotube photoanodes: establishing a beneficial back-contact by lift-off and transfer to titanium nitride layer
Lei Wang, Anca Mazare, Imgon Hwang +1
In this work we introduce the use of TiN/Ti2 N layers as a back contact for lifted-off membranes of anodic Ta3N5 nanotube layers. In photoelectrochemical H2 generation experiments…
