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.
The metastable 1T’ polymorph of MoS2 is an excellent catalyst towards the hydrogen evolution reaction. However, its production is limited by its lower energetic stability compared to the semiconductor 2H MoS2 phase. Stabilization of the 1T’ polymorph can be achieved through intercalation of sulfur-based compounds without adversely affecting its catalytic properties.
