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

3

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

4

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

5

Course Objectives: II

• Change from an undergrad to a professional– Tutorial style– Students responsible

for learning

Major Topics Continued• Introduction to surface reactions

– Rate laws– Mechanisms

8

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?

9
