Coordination Chemistry and Molecular Catalysis

The research in Martin Nielsen Group focuses on organometallic complexes for applications in sustainable chemistry. The group investigates homogeneous catalysis by designing new catalysts for renewable processes, with ongoing efforts in biomass valorization, carbon capture and utilization, and hydrogen storage. In addition, the group has a strong emphasis on homogenous polynuclear chemistry, studying well-defined transition-metal complexes and their unique cooperative properties.

Research

We explore ligand design, complexation, and the mechanistic features of organometallic catalysts that can enable efficient and selective transformations. Key contributions include advances in the design of polynuclear complexes with controlled electronic and structural properties.

Another line of research is devoted to supramolecular chemistry, particularly the synthesis of supramolecular cages that act as secondary coordination spheres for encapsulated organometallic complexes. These cages function as pseudo-enzymatic systems, offering new strategies for controlling reactivity and selectivity in catalysis.

Vacancies

Ongoing research projects involve mechanistic studies to uncover the origins of selectivity in CO₂ hydrogenation, as well as the development of high-entropy oxide catalysts for the reverse water-gas shift reaction.

Our group is also involved in Reformable, a pre-commercial DTU startup that deals with catalytic dry reforming of methane and CO2.
