Research
Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:
-
Transmission electron microscopy on live catalysts
The dissertation describes TEM experiments on heterogeneous catalysts.
-
Operando research in electrochemistry
The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

Palladium-catalyzed carbonylative synthesis of carboxylic acid anhydrides from Alkenes
Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

Will this discovery help us develop better catalysts?
Where exactly on the surface of a catalyst do the chemical reactions occur? Until now, it has always been a challenge to identify the exact locations of these ‘active sites’. In a new article in Nature, Leiden chemists helped their international colleagues reveal new insights into this issue. Their…

The electrochemical reduction of dioxygen and hydrogen peroxide by molecular copper catalysts
The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Skin Deep? Reading the Surfaces of the Body in Ancient Greek Literature and Science
The skin has recently gained attention within body studies for its many specific cultural and social associations, in addition to its biology. This project aims to examine the different layers of meaning and the functions invested in the skin in ancient Greece: how did ancient Greek literary and medical…

Fat-free mayonnaise thanks to manipulation of surface tension
Aqueous solutions of proteins and carbohydrates separate into two parts with an extremely ‘soft’ boundary surface. The surface tension between these two parts can be manipulated, for example by adjusting the pH balance. This can be used to develop emulsions of a water-based solution in another aqueous…

Experiments on CHD3 + Pt(111): New Insights into a Prototypical Gas–Surface Reaction
The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Poprhyrin-based metal-organic frameworks for the electrochemical oxygen reduction reaction
Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

Irene Groot receives Vidi grant: looking at catalysts at atomic scale
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…

Theoretical Chemistry
The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

may substantially affect rate of reaction relevant to Haber-Bosch catalysis
Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

Probabilities for Highly Activated Reaction of Polyatomic Molecules on Surfaces Using a High-Dimensional Neural Network Potential: CHD3 + Cu(111)
An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…
