Physical Chemistry, Solid State Chemistry, Surface Science and Catalysis — An atomic and molecular level understanding of surfaces is the key to understanding macroscopic surface phenomena like catalysis, adhesion, lubrication, and biocompatibility

Professor Somorjai's research interests are in the field of surface science. His group is studying the structure, bonding, and reactivity at solid surfaces on the molecular scale. This knowledge is then utilized to understand macroscopic surface phenomena; adsorption, heterogeneous catalysis, and biocompatibility on the molecular level. To this end, he also develops instruments for nanoscale characterization of surfaces. These include sum frequency generation surface vibrational spectroscopy (SFG) and high pressure scanning tunneling microscopy (high pressure STM) and high pressure X-ray photoelectron spectroscopy (ambient pressure XPS).

Since 1965, Professor Somorjai has proposed, planned, and carried out a program to build the fundamental molecular basis for the surface science of heterogeneous catalysis. He characterized the structure of clean metal single crystal surfaces and determined the structure and bonding of adsorbed molecules, and used them as model catalysts.  He synthesized and characterized metal and bimetallic nanoparticles in the 1-10 nm range and also used them as model catalysts as two-dimensional deposits or in three-dimensional form supported on mezoporous oxide or polymer surfaces and carried out catalytic reactions on these surfaces. He developed much of the instrumentation necessary for studying molecular surface chemistry and catalysis at high reactant pressures (atmospheres) on the small area crystals and nanoparticles. These include high pressure reaction cells that are combined with ultra high vacuum surface characterization chambers, sum frequency generation (SFG) vibrational spectroscopy, and scanning tunneling microscopy (STM), which can be used to monitor surfaces under reaction conditions, in situ. X-ray spectroscopy techniques that are synchrotron-based (ambient pressure XPS, NEXAFS and EXAFS) are also employed to monitor surfaces under reaction conditions.  The reactions studied include hydrocarbon conversion and found that catalytic selectivity depends on metal nanoparticle size and shape.  Small metal nanoparticles were found to be able to hetrogenize homogeneous solution phase catalytic reactions.  Solid-liquid biointerfaces are studied to determine the structures of amino acids and peptides.  Professor Somorjai has educated a generation of leading scientists in the field. Out of more than 130 Ph.D. students and 200 Posdoctoral Fellows, about 100 hold faculty positions.
