Research Interests

Though now Emeritus, Professor Delgass continues to collaborate with catalysis colleagues and their students. His long-standing interest in heterogeneous catalysis is aimed at understanding the surface chemical origins of catalytic activity and using fundamental knowledge gained from analysis of chemical kinetics, detailed surface chemical characterization and quantum-level theory in a model-based process called Discovery Informatics for the design and discovery of catalysts. Quantitative chemical kinetic evaluation comes from steady state reaction and transient isotopic tracing data, while a variety of spectroscopic measurements yield details of the catalyst chemistry. X-Ray photoelectron spectroscopy, for example, gives a quantitative chemical analysis of catalyst surfaces, and infrared spectroscopy reveals further details of the chemical state of the surface and the bonding of adsorbed species. Dehydrogenation and subsequent oligomerization of alkanes (CISTAR web site), partial oxidation of propylene to propylene oxide, catalysis by zeolites, and the water gas shift reaction are catalytic systems of current interest.

The work is part of the Purdue Catalysis Center, which fosters interaction among faculty and students in catalysis research groups by collaborating on research projects, sharing resources and facilities, and holding weekly joint group meetings.
