Ludo was raised in Deurne ( ), in the province Noord-Brabant in the south of the Netherlands. After finishing high-school in 1990, he went to Technical University Delft ( ) for a degree in Chemical Engeneering, where he left after finishing his propadeuse in 1992. He moved to Tiburg for a teacher training in Chemistry at the Hogeschool Katholieke Leergangen Tilburg ( ). He graduated there in 1995, having also spent 5 months working at New York University (New York, USA) in the research lab of Assis. Prof. Stacey F. Bent (now at Stanford University, ). While in New York, he got interested in continuing his education in the USA. He moved to the Boston area in August of 1995 for a Ph.D. program at Tufts University (Massachusetts, USA). He graduated with a Ph.D. in chemistry from the gas-surface dynamics group of Assoc. Prof. Arthur L. Utz ( ) in August 2000.
He moved back to the Netherlands to start a post-doctoral position in the research group of Prof. dr. Aart W. Kleyn, now the group of Prof.dr. Marc Koper.
Ludo's favorite molecule is methane.

Research Interests

Catalytic functionality of defects on metal surfaces

Metallic particles are catalysts to most industrial processes. On such particles, small terraces are interrupted by step and kink defects. Although decades of surface science, catalytic and gas-surface dynamics studies have revealed how gases react on smooth surfaces, little is known regarding the importance of steps and kinks to the overall kinetics and selectivity. My research focuses on just that! We use metal single crystal planes as models for real catalyst surfaces, ultrahigh vacuum and surface science technology, and supersonic molecular beam techniques. It’s an exciting area of research whose front runner, Gerhard Ertl, received the Nobel Prize in 2007.

In particular, we currently focus our attention on two sets of systems. The first investigates the influence of defects on activated adsorption. We are currently looking into H2 and CH4 dissociation on a variety of stepped surfaces using supersonic molecular beam techniques. We also employ both flat and cylindrical single crystal surfaces and currently look into reactivity as a function of surface structure and co-adsorbates. The second set of systems investigated adsorption of water on stepped surfaces, often in the presence of co-adsorbed hydrogen or water. Here, we are interested in learning about the effects of different types of steps and terrace widths in adsorption/desorption behavior of water and chemical reactions occurring at step and terrace sites.
