Beschreibung

The industrial chemistry group of Prof. Etzold at the Department of Chemistry, Technische Universität Darmstadt, offers a position as

Research Assistant/Ph.
D.

Student (all genders) - 67 %:
within the framework of a fixed-term employment contract initially limited to 36 months. The position is available from or at a mutually agreed date.

The research is part of the collaborative project "Laplace pressure controlled gas diffusion electrodes for organic electrosynthesis (GDE4OES)" funded by the Federal Ministry of Education and Research within the cluster4future "ETOS".

Within the research, the concept of pressure-controlled separation of an organic electrolyte and a gas phase is studied for complex mesh-based gas diffusion electrodes.

Background is, that with an organic electrolyte, a gas liquid separation based on wettability and thus materials properties is not possible.

Consequently, controlling the phase boundary and the catalyst wetting through the pressure difference, gets important. Within the PhD project, the electrocarboxylation of acetonitrile to cyanoacetic acid will be studied as test reaction. The scientific focus will be at the interface of chemical engineering and chemistry.

A lab test system shall be designed, that allows for precise control of the pressure difference, visualization of the gas and liquid permeation through the gas diffusion electrode as well as carrying out electrocarboxylation experiments.

Controls, data management and validation of the setup need to be realized.

The new test stand shall be applied to deduce the influence of mesh geometry, catalyst layer properties and process conditions on activity and selectivity of the test reaction.

The work will be embedded within several research projects at university and industry on the different aspects of the laplace controlled gas diffusion electrode and synergies through the close collaboration with these partners are expected.

The successful applicants will be enrolled as PhD student at TU Darmstadt.
