Catalysis with Green Technologies 

This module is concerned with understanding the importance of catalysis and also how this can be used as a tool for green chemistry. The module begins with introductory lectures on catalysis and green technologies, illustrating the very wide range of interesting and important applications of catalysis.  

Heterogeneous catalysis is of considerable importance to the chemical industry and this subject is discussed by a consideration of surface chemistry, modern techniques for studying surfaces and by the study of important organic and inorganic solid catalysts including the rapidly growing area of shape-selective catalysis.

Homogeneous catalysis is also an extremely important subject both in synthesis and industrial chemistry and this subject will be covered in a series of lectures on important metal-catalysed processes.  The important and growing areas of catalysis such as enzymatic and asymmetric catalysis will be explored for a range of important chemical reactions.

Case studies based on important catalytic processes will be used throughout the module and lectures will be supported by workshops.
