Characterization and properties of titanium dioxide based materials as PEMFC cathode supports and catalysts
(Universität Ulm, 2017-02-02)
The potential of alternative catalysts for application in the polymer electrolyte membrane (PEM) fuel cell relevant cathode reaction, the oxygen reduction reaction (ORR), was investigated using TiO2 based materials. Herein, ...
Sterically confined second-sphere receptor chromophores for optical molecular recognition and photocatalysis
(Universität Ulm, 2016-08-30)
The investigation of molecular processes and interactions through visible light is of fundamental importance for a wide range of technological and biological applications. The chromophores developed in this work have ...
"Development and optimization of bibenzimidazole transition metal chromophores for luminescent ion sensing and photocatalysis"
(Universität Ulm, 2016-10-19)
The recognition and fixation of highly reactive systems by binding within defined spatial geometries is a fundamental principle of the enlivened nature. In the last four decades this biologically tenet was transferred to ...
Corrosion resistant cathode catalyst support materials for polymer electrolyte membrane fuel cell
(Universität Ulm, 2017-08-08)
Polymer Electrolyte Membrane Fuel Cells (PEMFC) having high power density and low degradation are considered a viable option for future emission free mobility. In order to minimize the noble metal demand, platinum ...
Figures of photochemical/physical background in the context of solar energy conversion and storage: freely accesible and usable
(Universität Ulm, 2017-10-12)
The provided figures were created for the dissertation of Simon Kaufhold titled "Towards rational design of N-heterocyclic carbene bridged photochemical molecular devices for water reduction". The figures illustrate processes ...
Elektrochemische und bildgebende Untersuchungen zur Struktur der Phasengrenzfläche zwischen ionischen Flüssigkeiten und wohldefinierten Elektrodenoberflächen
(Universität Ulm, 2017-08-11)
The interface between ionic liquids and noble metal electrodes of well-defined surfaces, such as those of Au(100), Ag(100), Pt(100) and synthetic graphite, also known as HOPG, was characterized using basic electrochemical ...
Capturing Irradiation with Nano-antennae: Plasmon-induced Enhancement of Photoelectrolysis
(Universität Ulm, 2017-07-19)
Optimal harvesting of the natural solar spectrum for water splitting applications has led to adapting inadequate wide band gap semiconductors. Traditionally, this procedure has been widely explored in the past decades, ...
Towards rational design of N-heterocyclic carbene bridged photochemical molecular devices for water reduction
(Universität Ulm, 2017-11-09)
In order to achieve fair and easy access to energy for all and at the same time tackle climate change, the switch from fossil fuels to renewables is inevitable. Among renewable energy sources the energy delivered by the ...
Towards an artificial leaf – development of immobilizable photocatalysts
(Universität Ulm, 2017-01-13)
Modern society is confronted with two major challenges: energy supply and prevention of environmental pollution. The development of a novel energetic scenario based on the direct conversion of solar energy to storable solar ...
Untersuchungen zur elektrochemischen Metallabscheidung aus ionischen Flüssigkeiten: an Lithium, Titan und Dysprosium
(Universität Ulm, 2017-03-31)
Die fundamentalen Anfangsstadien der elektrochemischen Abscheidung von Lithium, Titan und Dysprosium auf Au(111) wurden in unterschiedlichen ionischen Flüssigkeiten untersucht und mit verschiedensten Methoden (CV, CA, ...
