Large surface area materials synthesis (M2R C5)

3EMR13 Large surface area materials synthesis (M2R C5) Materials and Chemistry S9
Lessons : 15 h TD : 0 h TP : 0 h Project : 0 h Total : 15 h
Co-ordinator : Guillaume Clet
Prerequisite
First and second year chemistry and/or materials science lessons
Course Objectives
To illustrate and understand the relationships between the synthesis modes and the textural properties of the specific large-area materials
Syllabus
1-Methods of synthesis
-What is the point of having specific high-surface materials?
-Some large families of materials: design of a divided material; bulk materials and supports; melted catalysts; Metal glasses; Alloys Raney catalysts; Industrial catalysts
-Methods of synthesis by precipitation and co-precipitation (principles and influence of parameters)
-Sol-Gel methods (chemical-physical bases, activation of precursor, polycondensation, gelling, ageing of frost, rinsing, drying, desolvation, stabilization of gels).

2-Porous Materials
-Zeolites: General characteristics; Reaction mixture (nature, role of the different constituents in the synthesis, concept of template); synthesis process and mechanisms; Post-Treatment and porosity creation (cation exchange, Déalumination, Désilication); New applications
-Mesoporous Materials: Synthesis (influence of parameters and surfactants); Functionalization
Practical work (TD or TP)
Acquisition of notions in the synthesis of materials of large surface specific, at the scale of the laboratory and industrial. Possibility to integrate the functionalized materials sector, including catalytic materials, and professions in related fields (heterogeneous catalysis, specialty chemistry, depollution, sensors...)
Acquired skills
-Knowledge of the various porous materials and their methods of obtaining
-Know how to choose a porous material for specific applications
-Know how to adapt a synthesis/modification mode to optimize the porosity of a material.
Bibliography
A specific bibliography is distributed during the sessions for each of the two parts of the course.
A useful work for the whole course:
- Handbook of heterogeneous catalysis ; G. Ertl, H. Knözinger, F. Schüth, J. Weitkamp (Eds.) ; Wiley-VCH, Weinheim (2008); Volume 1 en particulier.
