Thesis work for Bachelor, Master or Diploma
In order to increase the flexibility of renewable energies and improve their integration into existing energy networks, efficient intermediate storage is necessary. Hydrogen as the energy carrier of the future has a high potential. It is produced in high purity in a water electrolysis cell. Precious metal-free catalysts are of particular interest for an economic use of this technology.
This thesis is about the synthesis, characterization and optimization of support materials for the OER catalyst in a PEM electrolyzer.
During the thesis, support materials for OER catalysts will be synthesized, optimized and characterized physically as well as electrochemically.
A support material synthesis already known at the institute will be modified in a first step to influence the porosity of the material. Different structuring options will be investigated and in the following step Ir nanoparticles will be deposited on the support material in a hydrothermal synthesis. Physical characterization is to be carried out by e.g. XRD and BET surface area determination. For the electrochemical characterization, measurements on the rotating disk electrode as well as single cell measurements will be performed. In particular, the stability under continuous load on a potential is to be investigated.
