Chemical kinetics and reaction mechanisms on catalytic surfaces

Research in the Catalytic Nanoparticles Lab focuses on reaction mechanism studies on surfaces of solid catalysts for petroleum refining, chemical, pharmaceutical and related industries. The scale gap between observable reaction rates and catalytic surface reactions on the molecular level is bridged through iterative cycles of experimental catalyst characterization and testing in combination with quantum chemical calculations. Experimental information establishes the basis for the selection of models and the level of theory for quantum chemical calculations and then, in turn, computational results help to deconvolute and better interpret experimental data. In contrast with traditional catalyst models that assume a static surface, our approach of combining kinetic studies, IR and Raman spectroscopic measurements and quantum chemical calculations with vibrational analyses allows us to develop new methodologies for describing dynamic catalytic surface changes under reaction conditions and, consequently, for a transformational improvement in the description, control and further development of catalytic processes.
