This course explores topics in the design of heterogeneous catalysts for environmentally benign chemical processes. The class includes lectures on the concepts in catalyst preparation, catalyst characterization, and microkinetic analysis of catalytic processes. We show how experimental and theoretical approaches allow elucidation of important reactive intermediates and transition states involved in chemical reaction pathways. With this information, we show how to identify possible new catalysts that may facilitate reactions of interest, but do not enhance undesirable reactions (that lead to low efficiency or to pollution). Additionally, the class meets weekly to work as a team on applying these concepts to designing new catalysts for such processes as selective dehydrogenation of hydrocarbons, selective catalytic reduction of nitric oxide, and selective reduction of fluoro-carbons. Students will also do experimental work in the catalysis labs to test the catalyst designs that they have developed during the semester.
