Nanoscience and Nanotechnology for Energy Applications
Prof. Thomas Wågberg
We are an interdisciplinary research team comprising physicists and chemists with both experimental and theoretical expertise. We work with diverse carbon nanomaterials such as fullerenes, single- and multiwalled carbon nanotubes, carbon fibers, and graphene, but also advanced metal nanoparticles.
Composites of these materials are utilized as advanced catalysts in energy applications for oxygen reduction, water oxidation, Li-ion batteries but also for biosensors, organic solar cells, and field effect transistors.
Here we report the use of a molecule-to-cluster strategy for preparing ultrasmall (~8 Å) trimetallic Co-Fe-W clusters with high efficiency for the OER in alkaline media. Besides the excellent performance as OER catalyst, our molecule-to-cluster strategy allows to achieve well-defined transition-metal clusters in the subnanometer regime.
