This program elucidates the steps involved in plasmonically driven photochemistry, specifically hot carriers (both electrons and holes) created by the decay of plasmons into one or more electron-hole pairs. The plasmons provide a way to efficiently capture light and convert into a number of different energy storage forms. The energetic carriers resulting from plasmon decay are available to drive chemical reactions that would otherwise be energetically inaccessible, slow, or nonspecific. As such, it will have implications for significant efficiency gains in a wide range of chemistries relevant to the areas listed below. However, this program focuses on the mechanistic fundamentals, rather than a specific chemistry.
