The Green Lab probes the surface chemistry of novel nanoparticle catalysts. Surface chemistry is involved in the production of almost all synthetic materials in our lives through heterogeneous catalytic reactions. It is also a dominant factor in environmental remediation such as the catalytic exhaust systems used in automobiles. Our lab employs low temperature in situ transmission infrared (TIR) spectroscopy to study chemical reactions in real-time over novel nanoparticle catalyst surfaces. One current project studies a group of gold-core-oxide-shell (Au@TiO2) nano-catalysts showing promise as efficient thermo- and photo- catalysts for oxidation reactions. By comparing catalytic performances of similar Au@TiO2 nanoparticles with subtle design differences such as gold loading, shell thickness, and nanoparticle size, the Green Lab is able to provide crucial insights into future catalyst design and optimization.
