Influence of the electrode nano/microstructure on the electrochemical properties of graphite in aluminum batteries
Giorgia Greco, Dragomir Tatchev, Armin Hoell +4
Herein we report on a detailed investigation of the irreversible capacity in the first cycle of pyrolytic graphite electrodes in aluminum batteries employing 1-ethyl-3-methylimidaz…
Open top anodic Ta3N5 nanotubes for higher solar water splitting efficiency
Sabina Grigorescu, Seulgi So, Jeong Eun Yoo +3
In the present work we grow self-organized Ta2O5 nanotube layers in a H2SO4/NH4F electrolyte at various elevated temperatures. Under optimized conditions we obtain 4 μm long nanotu…
Bipolar Anodization Enables the Fabrication of Controlled Arrays of TiO2 Nanotube Gradients
G. Loget, S. So, R. Hahn +1
We report here a new concept, the use of bipolar electrochemistry, which allows the rapid and wireless growth of self-assembled TiO2 NT layers that consist of highly defined and co…
Tungsten doping of Ta3N5-Nanotubes for Band Gap Narrowing and Enhanced Photoelectrochemical Water Splitting Efficiency
Sabina Grigorescu, Benedikt Baerhausen, Lei Wang +4
Ordered W-doped Ta2O5 nanotube arrays were grown by self-organizing electrochemical anodization of TaW alloys with different tungsten concentrations and by a suitable high temperat…
Optimization of efficiency and energy density of passive micro fuel cells and galvanic hydrogen generators
Robert Hahn, Stefan Wagner, Steffen Krumbholz +1
A PEM micro fuel cell system is described which is based on self-breathing PEM micro fuel cells in the power range between 1 mW and 1W. Hydrogen is supplied with on-demand hydrogen…
