An elective 3-lecture course that introduces applied chemistry students to different aspects of chemical catalysis. Both theory and applications of catalysis are included. The course covers different types of homogeneous, heterogeneous and hybrid types of catalysis. Catalysis by molecular organometallic compounds and zeolites is involved together with surface catalysis by metals and metal oxides. Photocatalysis is also included. Applications of catalysis in organic reactions such as hydrogenation, reforming, carbonylation, isomerization, and other petrochemical processes are included. Environmental applications of catalysis, such as cleanup processes by solar light and CO oxidation are also included.
