TITLE Catalysis

 
LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
ECTS CREDITS 5

 
DEPARTMENT Chemistry

 
DESCRIPTION A review of kinetics and catalysis
Catalysis in solution
The Hammet relationship
Specific Examples of Catalysis in solution
Surface properties of the solid state

Physical techniques in the study of surfaces:
• Surface structure determination: low energy electron diffraction (LEED)
• Vibrational spectroscopy at surfaces: reflection absorption infrared spectroscopy (RAIRS) and electron energy loss spectroscopy (EELS)
• Electronic structure of adsorbates/substrates: X-ray photoelectron spectroscopy (XPS), ultra-violet photoelectron spectroscopy (UPS) and Auger electron spectroscopy (AES)
• Scanning tunnelling microscopy (STM) and atomic force microscopy (AFM)

Adsorption-desorption equilibria: kinetics of adsorption; energetics of adsorption
A review of different adsorption isotherms
Mobility on Surfaces
Eley Rideal mechanism of surface reactions
Langmuir-Hinshelwood mechanism
The significance of the volcano curve
Specific examples of catalysis in industrial processes

Study-unit Aims:

The study-unit aims to give students an insight into both homogeneous and heterogeneous catalytic processes and to give them an understanding of different tools by which surfaces used for catalytic purposes can be studied.

Learning Outcomes:

1. Knowledge & Understanding:
By the end of the study-unit the student will be able to:

Demonstrate an understanding of kinetics of catalytic processes;
Demonstrate an understanding of the surface properties of solids;
Demonstrate an understanding of various techniques to study surfaces;
Demonstrate an understanding of the mechanisms of homogenous and heterogeneous catalysis;
Demonstrate a qualitative and quantitative understanding of adsorption isotherms in terms of both kinetic and energetic perspectives.

2. Skills:
By the end of the study-unit the student will be able to:

Manage data/information and propose solutions to problems.
