Studying at York
Catalysis with Green Technologies - CHE00032H
- Department: Chemistry
- Credit value: 20 credits
- Credit level: H
- Academic year of delivery: 2022-23
- See module specification for other years: 2023-24
Module summary
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 combines surface chemistry and 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. Hot topics will round off the module with the latest research and challenges in the area

Module aims
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.
Module aims:
-
Develop in-depth knowledge of catalytic processes and their relevance to industry
-
Train students on the use and application of heterogeneous, homogeneous, asymmetric and enzymatic catalysts
-
Develop an understanding of how sustainable catalytic processes are relevant to green chemistry

Module feedback
Exam results with per-question breakdown are returned to the students via supervisors within 5 weeks (as per special approval by the University Teaching Committee). Outline answers are made available via the Chemistry web pages when the students receive their marks, so that they can assess their own detailed progress/achievement. The examiners’ reports for each question are made available to the students via the Chemistry web pages
Students will receive feedback on their performance in the workshop assessment. They will receive verbal feedback on their progress in the formative workshops, which support lectures.
