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…
Black TiO2 nanotubes formed by high energy proton implantation show noble-metal-co-catalyst free photocatalytic H2-evolution
Ning Liu, Volker Häublein, Xuemei Zhou +8
We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic ce…
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…
Graphitic C3N4 Sensitized TiO2 Nanotube Layers: A Visible Light Activated Efficient Antimicrobial Platform
Jingwen Xu, Yan Li, Xuemei Zhou +4
In this work, we introduce a facile procedure to graft a thin graphitic C3N4 (g-C3N4) layer on aligned TiO2 nanotube arrays (TiNT) by one-step chemical vapor deposition (CVD) appro…
Visible Light Triggered Drug Release from TiO2 Nanotube Arrays: A Novel Controllable Antibacterial Platform
Jingwen Xu, Xuemei Zhou, Zhida Gao +2
In this work, we use a double-layered stack of TiO2 nanotubes (TiNTs) to construct a visible-light triggered drug delivery system. Key for visible-light drug release is a hydrophob…
Hydrogenated anatase: Strong photocatalytic H2 evolution without the use of a co-catalyst
Ning Liu, Christopher Schneider, Detlef Freitag +8
In the present work we show, how a high pressure hydrogenation of commercial anatase or anatase/rutile powder can create a photocatalyst for hydrogen evolution that is highly effec…
