Double-Side Cocatalytic Activation of Anodic TiO Nanotube Membranes with Sputter-Coated Pt for Photocatalytic H Generation from Water-Ethanol Mixtures
Gihoon Cha, Marco Altomare, Nhat Truong Nguyen +3
Self-standing TiO nanotube layers in the form of membranes are fabricated by self-organizing anodization of Ti metal and a potential shock technique. The membranes were then de…
One-dimensional Titanium Dioxide Nanomaterials: Nanotubes
Kiyoung Lee, Anca Mazare, Patrik Schmuki
In the present review we try to give a comprehensive and most up to date view to the field, with an emphasis on the currently most investigated anodic TiO2 nanotube arrays. We will…
High-Temperature Annealing of TiO2 Nanotube Membranes for Efficient Dye-Sensitized Solar Cells
Fatemeh Mohammadpour, Marco Altomare, Seulgi So +5
We fabricate photo-anodes by transferring anodic TiO2 nanotube membranes in tube-top-down configuration on FTO glass, and use them for constructing frontside illuminated dye-sensit…
Molten o-H3PO4 - A New Electrolyte for the Anodic Synthesis of Self-Organized Oxide Structures: WO3 Nanochannel Layers and Others
Marco Altomare, Ole Pfoch, Alexei Tighineanu +4
We introduce the use of pure molten ortho-phosphoric acid (o-H3PO4) as an electrolyte for selforganizing electrochemistry. This electrolyte allows for the formation of self-organiz…
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…
A Comparison of Anodic TiO2 Nanotube Membranes used for Front-side Illuminated Dye-Sensitized Solar Cells
Fatemeh Mohammadpour, Mahmood Moradi, Gihoon Cha +4
In the present work we compare TiO2 nanotube lift-off strategies for the construction of front-side illuminated dye-sensitized solar cells (DSSCs). Anodic nanotube layers were deta…
Topographical study of TiO2 nanostructure surface for photocatalytic hydrogen production
Gihoon Cha, Kiyoung Lee, JeongEun Yoo +2
In the present work we investigate the photocatalytic hydrogen production (water splitting) activity of different Pt loaded TiO2 nanotube layers. Therefore, we fabricate free stand…
