Research Interests

Nanoscience is the study and manipulation of materials on an atomic level. Due to the high ratio of atoms located on the surface of the nanoparticles (particles between one and a few hundred nanometers in diameter or between tens to thousands of atoms), these materials behave differently than bulk. Transition metals have long been utilized extensively in the area of catalysis, especially for surface-catalyzed reactions. Therefore, the high surface area of transition-metal nanoparticles is conducive to higher catalytic efficiencies than normally seen in bulk metals.

Professor Petroski's research is involved with studying the catalytic efficiency of transition metal nanoparticles, predominantly platinum and gold, by using Attenuated Total Reflectance – Fourier Transform Infrared Spectroscopy (ATR – FTIR). FTIR spectroscopy will provide structural information about the molecules on the surface of the metal nanoparticles. The addition of the ATR accessory will allow us to study the nanoparticles in solution so we can observe a particular catalyzed reaction directly and in real time. The reaction mechanism determined from the spectra will provide not only structural changes to the reactants but kinetic data as well. Being able to achieve this type of detailed information for a reaction will allow for the design of more efficient catalytic nanostructured materials.
