Catalyzing Change: Scratching the Surface of Sustainable Materials for Climate Solutions
PhD defence, Wednesday 6 December, Jens Jakob Gammelgaard
During his studies Jens Jakob Gammelgaard investigated novel materials composed of abundant elements including carbon, nitrogen and transition metals. Development of effective catalytic materials without the use of scarce noble metals such as platinum is a requirement for finding a solution to the ongoing climate crisis. To that end, an increased understanding of the relationship between the structure of a catalyst and its activity has been pursued during the studies. This has been achieved using a model system under ultra-high vacuum conditions, allowing for the use of powerful microscopy and spectroscopy techniques. These methods have been used to study a novel catalyst composed of cobalt, carbon and nitrogen. The catalyst was studied for its properties within oxygen reduction, an important reaction for the development of fuel cells.
The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.
