  3. Overview of Today's Lecture • Background • Course objectives • Organization • Requirements • Grading

  4. Background • Surfaces reactions everywhere • Washing clothes • Brushing teeth • Preventing food to stick to pans • Surface chemistry important to a wide range of technologies • Catalysis • Semiconductor Fab • Paints & finishes • Consumer products

  5. Course Objectives • Provide students with a fundamental understanding of adsorption on reactions on solid surfaces • Review background material on crystal structure, stat mech • Provide a basis to understand catalysis

  6. Course Objectives: II • Change from an undergrad to a professional • Tutorial style • Students responsible for learning

  7. Major Topics Continued • Review of surface structure • Adsorption • Binding of molecules to surface • Adsorption isotherms • Structure of adsorbed layers • Kinetics of adsorption

  8. Major Topics Continued • Introduction to surface reactions • Rate laws • Mechanisms

  9. Major Topics Continued Catalysis • How do catalysts work? • Mechanisms of catalytic action • Kinetics of catalytic reactions • Mass transfer in catalysis • Metal catalysts • What do they do, how do they work?

  10. Major Topics Continued • Background material • Statistical mechanics • Quantum methods • Why do reactions have barriers • Prediction of mechanisms

  11. Class schedule • MW – lecture, Fri group tutorials • No class – Feb 11, 18, Mar 19, 22, 24, 26, May 3 • Tutorials – Jan 30, Feb 13, 27, Mar 12, Apr 2, 16, 30 • Four groups, Fri 10:30, 11, 11:30, 12 • Midterm March 3 • Final 8-11 am Friday May 14

  12. Organization • Class will divide into 4-5 person squads • Squads will work together on homework and hand in group assignments • Squads will meet together with Masel for a 30 minute tutorial. (Fri 10:30, 11, 11:30, 12) Jan 30, Feb 13, 27, Mar 12, Apr 2, 16, 30 Please divide yourselves into squads today and pick a time for a tutorial

  13. Requirements • Midterm • Final • Homework almost every week • Each group should work together on the assignment and hand in one group report. • Tutorials

  14. Textbook Principles of Adsorption and Reaction On Solid Surfaces Richard I Masel Wiley 1996

  15. References • Chemical Kinetics and Catalysis by Rich Masel

  16. Grading • Midterm 40% • Final 50% • RIM Judgment 10%

  17. My Grading Philosophy • I like to give A's – but students have to earn them

  18. Course Policies • No whining • No whining • No whining • Chill out

  19. Course Policies • Encouraged to work together on homework • Closed book/notes exams • Sample exam questions on the web • No whining

  20. Misc. Course Info • Course notes will be available at http://www.scs.uiuc.edu/~che553 • Please download lect prior to class • Exams will include essay questions, questions that require critical thinking e.g. compare and contrast … • Sample exam questions will be on the website
