Quantum Dot Photocatalysis
This talk will describe the use of cadmium sulfide quantum dots (CdS QDs) – single crystals of CdS with diameters of ~3 nm – as visible-light photocatalysts for the reduction of nitrobenzene to aniline through six sequential photoinduced, proton-coupled electron transfers in water. Transient absorption spectroscopy and nuclear magnetic resonance (NMR) are used to analyze the mechanisms of molecular adsorption to the QD, and to show us how the environment at the surface of the QD promotes chemical transformations.
