Advanced Inorganic Chemistry: Adsorption, Interfaces, Heterogeneous Catalysis [SCHIM103]

Learning outcomes

This course describes both surface chemistry and colloidal chemistry as well as liquid-liquid, liquid-solid and gas-solid interactions. Theoretical concepts will be used for understanding the kinetics and reaction mechanisms of heterogeneous catalysis.

At the end of this course, the student will be able to:

For part 1.

• Establish the relationship between surface tension and other thermodynamic variables

• Analyze the variation of surface tension with temperature

• Understand the pressure of curved surfaces and the capillary effect and vapor pressure on a curved surface

• Understand the molecular nature of the interfacial region between different phases

• Establish the different equations: Interfacial tension and its variation with concentration

• Understand internal pressure and its relationship to surface tension

• Understand the nature of adsorption (physical and chemical)

• Analyze the energy variation during adsorption and activation energy

• Determine the adsorption rate

• Understand the physico-chemistry of surfactants: classification, characteristics and dissolution of a surfactant

For part 2.

• Describe the characteristics of a heterogeneous catalyst

• Understand the chemical kinetics of a reaction that takes place on the surface of a heterogeneous catalyst

• Describe the main kinetic equations

• Analyze the adsorption steps at the surface

• Analyze and compare the activity of a catalyst with other reference solids (qualitatively and quantitatively)

• Understand the principles as well as the stabilization mechanisms of the different colloidal systems

Objectives

This course describes surface chemistry and colloidal chemistry as well as liquid-liquid, liquid-solid and gas-solid interactions. Theoretical concepts will be used for understanding the molecular nature of the interfacial region, phenomena and kinetics and mechanisms of adsorption on solid surfaces and reaction of heterogeneous catalysis. The main objective of the course is to stimulate student reflection. The introduction of a new concept or a new theory often begins with the presentation of a problem, a phenomenon encountered or an observation in nature or in everyday life.
