Award: HI ERN doctoral student receives Best Poster prize
Lyon (France), September 8, 2023 - HI ERN PhD student Miklós Márton Kovács has been honored with the Best Poster Award at the 74th Annual Meeting of the International Society of Electrochemistry (ISE) in Lyon, France.
In his poster titled "Electrospun Nanofiber Catalyst Materials for Oxygen Evolution Reaction (OER) in Acidic Water Electrolysis" he presented a non-conventional method for the fabrication of Iridium oxide (IrOx) based materials for water electrolysis. Iridium is a catalytically active material, that is very expensive. To make efficient use of it, it is important to have it in a structure, where most of the substance is active and at the surface. Nanofibers are such a morphology that can possibly decrease the amount needed.
Miklós Márton Kovács showcased two main fields of his research:
On the one hand he described the catalyst synthesis by electrospinning and further calcination which can be an alternative method to produce IrOx-based catalyst materials. On the other hand he visualized the characterization of this porous nanofiber mat. The latter was investigated by the setup of a scanning flow cell (SFC) coupled with inductively coupled plasma mass spectrometry (ICP-MS) which had been developed at HI ERN in the department of Prof. Dr. Karl Mayrhofer. The investigation focuses on the electrochemical activity and the dissolution of the IrOx catalyst materials. Main impact of the calcination environment on the catalyst behaviour was observed. According to this result, concerted effort may be taken to apply existing materials of different morphologies as an alternative for the synthesis of novel complex mixed metal oxides.
Miklós Márton Kovács studied chemical and process engineering at the Karlsruhe Institute of Technology (KIT) and has been working on his doctorate at HI ERN in the research group High-Throughput Electrocatalysis since completing his master study in 2021. Hereby, he is studying the electrochemical activity and dissolution behaviour of non-conventional anode materials of polymer electrolyte membrane water electrolysers (PEMWE) in a high-throughput manner using the SFC-ICP-MS setup.
His research enables a fundamental insight into catalysis and catalyst utilization in electrochemical devices in general and provides new means of research for high performance electrocatalyst materials.
