Department of Chemistry Seminar

April 15 @ 4:10 pm - 5:00 pm

Professor Charles Campbell, University of Washington, Departments of Chemistry and of Chemical Engineering
Hosted by Prof. David Lee

Reaction Energies on Surfaces of Catalysts and Electrocatalysts

Late transition metal surfaces catalyze a wide variety of industrially important reactions.  Experimental measurements of the thermodynamics of surface chemical reactions of importance in catalysis and electrocatalysis by late transition metals will be reviewed.  Topics include:  (1) calorimetric measurements of the adsorption energies of small molecules and molecular fragments on single crystal transition metal surfaces in the gas phase, and their comparisons to different DFT methods that reveal average errors in DFT exceeding 20 kJ/mol; (2) measurements of adsorption energies in aqueous phase and analysis of the differences with respect to gas phase, (3) measurements of the entropies of adsorbates and their trends; (4) measurements of the energies of transition metal atoms in nanoparticle catalysts on different support materials, analysis of their strong dependences on particle size and support, and the correlation of these metal-atom energies with catalyst performance.
