05-MCM-CC Surface Chemistry & Catalysis

Introduction to the concepts and foundations of surface chemistry and heterogeneous catalysis
- Basic questions and concepts of heterogeneous catalysis
- Different types of het. catalysts
- Preparation of catalysts according to different target variables
- Use of het. catalysts in industry: chemical engineering issues
- Mass transport limitation and diffusion
- characterization of pores
- reaction mechanisms of het. catalyzed reactions
- Understanding of het. catalyzed reactions: study of surface reactions under ultra-high vacuum conditions
- Gas flow (types of gas flow, inner friction, diffusion of gases, vacuum regimes)
- Vacuum technology (pumps, pressure gauges, materials, design and of vacuum systems)
- Mass spectrometry (for residual gas analysis and temperature programmed spectroscopies)
- Cryogenics (Methods of cooling, physical and chemical phenomena at low temperature)
- Safety issues
- Hands-on setup of a small vacuum system from components
- Supervised experiments involving sample preparation and the application of standard surface science tools in ultra-high vacuum

Passing this module, the students should be able to understand, describe and use topics of the following areas:
• principles of catalysis at surfaces
• types and preparation of het. cat.
• kinetic description of surface reactions and microscopic understanding of electronic factors influencing adsorption and reaction on metals
• diffusion in porous materials and impact
on the performance of cat.
• basic principles of vacuum technology
• basic principles of cryogenic techniques
In addition, the students will gain hands-on experiences in using vacuum systems and competences in the preparation of presentations including literature research for a new topic
