Ball model illustrating the state of a model catalyst particle after exposure to a reductive environment representative of that present in a real, working catalyst.

During her studies, Signe Strange Grønborg investigated the catalytic and electronic properties of single layer MoS2. MoS2 has been used for decades in the hydrodesulfurization industry to remove sulfur from crude oil to prevent acid rain. More recently, single layer MoS2 has been subject to great scientific interest due to its exotic electronic properties.

Signe studied how the catalytically active nanoparticles of single layer MoS2 interacts with molecules relevant for hydrodesulfurization. She has developed a new approach for synthesis of large, single layer MoS2 islands for detailed investigations of the electronic properties of single layer MoS2.

The new research findings contribute to the understanding of the catalytic mechanism of the hydrodesulfurization under working conditions as well as a detailed insight to the electronic properties of single layer MoS2.

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO) at Aarhus University.

This résumé was prepared by the PhD student.
