My research group and I are interested in understanding the reaction chemistry of transition element compounds with particular emphasis on their role in catalysis. Our investigations are aimed at building mechanistic understanding that can advance our knowledge of catalysts and improve their design. We determine reaction mechanisms by studying chemical kinetics, characterizing intermediates, employing state-of-the art spectroscopy under operando conditions, and developing structure-function correlations.
One of my laboratory’s hallmarks is that we combine mechanistic/physical studies and synthetic chemistry. We are currently engaged in three projects that span fundamental atom and electron transfer reactions in porphyrin/heme systems, catalytic conversion of biomass, and kinetics of single-site olefin polymerization catalysts. Our research is funded by external grants from the Department of Energy and the National Science Foundation. Highlighted below are our most recent accomplishments.
Major Research Accomplishments of the Abu-Omar Group:
- Discovered rhenium catalyzed DeOxyDeHydration reaction (DODH) and applied its utility to conversion of biomass-derived molecules such as glycerol and sugar alcohols to small and useful organics (SUO).
- Developed synergistic and tandem catalysis for conversion of lignin to aromatic compounds using synergistic effects between Pd nanoparticles and divalent zinc Lewis acid.
- Established the chemical mechanism for the biological detoxification of chlorite to innocuous chloride and dioxygen with the heme enzyme chlorite dismutase.
- Demonstrated the use of manganese and ruthenium water-soluble porphyrin complexes as catalysts for generation of chlorine dioxide from chlorite under ambient temperature and neutral pH.
- Established the utility of molecular weight distribution (MWD) as a tool for studying and defining the kinetics of single-site olefin polymerization catalysts.
