Description du contenu de l'enseignement

Get a basic knowledge in surface chemistry and heterogeneous catalysis : ranging from the fundamental to a faced targeted reaction

Structural and electronic properties of solid surfaces
1. Thermodynamics : surface vs. Bulk
2. Electronic properties of surfaces
3. Structures of surfaces : Woods’ notation, Matrix notation, Relaxation, Reconstruction
4. Surface characterization techniques : XPS, UPS, STM, AFM, TPD, TPR
Fundamentals of adsorption and heterogeneous catalysis
1. Definitions : physisorption, chemisorption, adsorption isotherms, reversibility principle, TOF / TON, conversion, Selectivity.
2. Adsorption isoterms (Langmuir, Temkin, Frumkin, BET) ; Adsorption kinetics
3. Kinetics of surface reactions
  ¿Elementary steps, external and internal mass transfer (Thiele-Weisz modulus), rate determining step, Langmuir-Hinshelwood, Eley-Rideal, Boudart (MASI : most abundant surface intermediate).
Industrial Catalyst
Types of Supports – active phase preparation (impregnations, coprecipitation, solgel), isoelectric point, SMSI
Irational design of a catalyst
Iterative process, methodology for characterisation (prior, during and after reaction).
Zeolites and acid catalysis
Synthesis routes, main catalytic applications, superacidity ; carbocations ; other solid acids ; mesoporous solids (SBA-15, M41S).
