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…
Stable Co-Catalyst-Free Photocatalytic H2 Evolution From Oxidized Titanium Nitride Nanopowders
Xuemei Zhou, Eva M. Zolnhofer, Nhat Truong Nguyen +3
In the present work, a simple strategy is used to thermally oxidize TiN nanopowder (ca. 20 nm) to an anatase phase of a TiO2:Ti3+:N compound. In contrast to the rutile phase of suc…
Use of Anodic TiO2 Nanotube Layers as Mesoporous Scaffolds for Fabricating CH3NH3PbI3 Perovskite-based Solid State Solar Cells
Raul Salazar, Marco Altomare, Kiyoung Lee +7
We optimize the deposition of CH3NH3PbI3 perovskite into mesoporous electrodes consisting of anodic TiO2 nanotube layers. By a simple spin coating approach, complete filling of the…
Aligned metal oxide nanotube arrays: key-aspects of anodic TiO2 nanotube formation and properties
Francesca Riboni, Nhat Truong Nguyen, Seulgi So +1
Over the past ten years, self-aligned TiO2 nanotubes have attracted tremendous scientific and technological interest due to their anticipated impact on energy conversion, environme…
Efficient Photocatalytic H2 Evolution: Controlled Dewetting-Dealloying to Fabricate Site-Selective High-activity Nanoporous Au Particles on Highly Ordered TiO2 Nanotube Arrays
Nhat Truong Nguyen, Marco Altomare, JeongEun Yoo +1
Overlaid self-ordering processes: we form anodic self-organized TiO2 nanostumps and exploit them for self-ordering dewetting of Au-Ag sputtered films. This forms ordered particle c…
Controlled spacing of self-organized anodic TiO2 nanotubes
Selda Ozkan, Nhat Truong Nguyen, Anca Mazare +1
We report on how to grow and control self-organized TiO2 nanotube arrays that show defined and regular gaps between individual nanotubes. For this we use electrochemical anodizatio…
Aminated TiO2 nanotube as a Photoelectrochemical Water Splitting photoanode
Seyedsina Hejazi, Nhat Truong Nguyen, Anca Mazare +1
The present work reports on the enhancement of TiO2 nanotubes photoelectrochemical water splitting rate by decorating the nanostructure with an amine layer in a hydrothermal proces…
Anodic TiO2 nanotube layers: why does self-organized growth occur - A mini review
Xuemei Zhou, Nhat Truong Nguyen, Selda Ozkan +1
The present review gives an overview of the highlights of more than 10 years of research on synthesis and applications of ordered oxide structures (nanotube layers, hexagonal pore…
