Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

The research aim of the Catalysis and Surface Chemistry group headed by Prof. Marc Koper is to probe and understand chemical reactions on well-defined, mostly single crystalline, surfaces at the molecular level.

Coordination chemistry is the chemistry of metal atoms "coordinated" by other atoms, ions or molecules. Important challenges in the research on coordination and organometallic chemistry are to understand the relation between the ligand and metal complex structures and the (catalytic) properties of the…

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

The dissertation describes TEM experiments on heterogeneous catalysts.

Can we tailor catalysts at the atomic scale by means of high-school chemistry and geometry rules?

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

During the 20th anniversary meeting of the Netherlands' Catalysis and Chemistry Conference, Marc Koper received the Netherlands Catalysis and Chemistry Award. ‘The ultimate candidate for the prize’, it says in one of the recommendation letters.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

Chemist Irene Groot has been awarded a TA grant. Together with Shell, Leiden Probe Microscopy, DSM Resolve and Utrecht University, Groot will conduct research into catalysts for the production of raw materials and fuels.

Surface Reaction Barriometry: Methane Dissociation on Flat and Stepped Transition-Metal Surfaces.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Catalysts are indispensable in everyday life. We know what they do and more or less how they do it, but we still lack a fundamental understanding about their functioning at an atomic scale. Therefore, Irene Groot from the Leiden Institute of Chemistry develops new measuring techniques to unravel the…

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model for the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a unique curved platinum surface, Ludo Juurlink and PhD candidate Richard van Lent from…

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

How can rare and expensive materials be used more efficiently to produce cleaner and cheaper fuel? Under the guidance of Marc Koper, Professor of Catalysis and Surface Chemistry, international teams of scientists have published 3 articles in Nature Communications.

The electrochemical reduction of a group of organic compounds on platinum is strongly dependent on the arrangement of the atoms in the platinum surface. Christoph Bondue, postdoc in Marc Koper's group, published this in Nature Catalysis on 4 March. The reduction of such compounds is an important process…
