Henrik Særkjær Jeppesen

During his PhD studies, Henrik S. Jeppesen researched the connection between the structures of layered materials and how it could impact their properties, such as photocatalysis. Where photocatalysis, ideally, utilises sunlight to perform chemical reactions acts as the green alternative to the regular catalysis being used worldwide and is often a highly energy intensive process. Henrik S. Jeppesen studied two types of materials, namely thiostannates and bismuth oxyhalides, where the former is based on the natural occurring SnS2 material was investigated for the light absorbing properties based on structures. Bismuth oxyhalides were investigated for their high photocatalytic efficiencies based on their structures and synthesis conditions. The new research findings contribute towards the design of future catalyst by diving deep in understanding the materials at their core.

The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
