My research interests revolve around materials chemistry and involve a variety of functional nanostructured inorganic materials including semiconductors, organic-inorganic hybrids, and ceramics as well as molecular compounds including clusters, transition metal complexes, and single-site catalysts relevant to a variety of energy-related applications. Throughout the years, I have developed expertise and experience with homogeneous and heterogeneous photocatalysts and I am now especially interested in designing hybrid photosystems that combine the advantages of both approaches.

My main research activities are closely related to the following projects of our research division:

• Fundamental studies (kinetics, mechanisms, light-matter interactions)
• New concepts in photocatalysis

Within the framework of a national Austrian Science Fund (FWF) Stand-Alone Project P32801 “Surface-Immobilized Molecular Chalcogen-based Metalate Clusters for Photocatalysis” (2020-2024), my team now explores all-inorganic clusters in light-driven catalytic applications, aiming to generate green hydrogen and other solar fuels.

Two Ph.D. students (Samar Batool and Stephen N. Myakala) are fully funded for the period of the project. In addition, many other group members are involved as a part of their Master’s Thesis or Ph.D. work.
