Interfaces and Catalysis (390281)

The goal of “Interfaces and Catalysis” is to gain insight and understanding in the fundamental aspects of interfaces, colloidal systems and catalytic reactions and the use this knowledge in practice.

Interfaces and Catalysis starts with an empirical description of chemical kinetics and the relation with possible reaction mechanisms. Subsequtenly the following topics are studied:

  • Properties of surfaces and interfaces (solid-liquid, solid-gas, liquid-gas)
  • Propeties of colloidal systems
  • (Mathematical) description of adsorption and desorption
  • (The rate of) catalytic reactions
  • Mass transfer limitations
  • Characterization techniques
  • Wetting properties (contact angle)
  • Stability of colloidal systems
  • Modifications of surfaces and interfaces

After following the course students should be able to:

  • Determine kinetic parameters (like the activation energy or half life time of a reaction, rate constant of a reaction of the order) from experimental data.
  • Explain the influence of external mass transfer, internel mass transfer, adsorption , reaction at the surface and desorption on the experimentally observed reaction rate, kinetics and selectivity.
  • Describe the core-principles in colloid chemistry, like surface tension, adsorption, wetting, surface energy, electro-osmosis en electrophoresis, colloidalstability.
  • Use expressions for capillary rise, surface polarity, critical surface tension, electric double layers on experimental data.
  • Use the gained knowledge from catalysis and colloid chemistry on an integrated case study.
