Hydrated Electron Generation by Excitation of Copper Localized Surface Plasmon Resonance
(2019) In Journal of Physical Chemistry Letters 10(8). p.1743-1749- Abstract
Hydrated electrons are important in radiation chemistry and charge-transfer reactions, with applications that include chemical damage of DNA, catalysis, and signaling. Conventionally, hydrated electrons are produced by pulsed radiolysis, sonolysis, two-ultraviolet-photon laser excitation of liquid water, or photodetachment of suitable electron donors. Here we report a method for the generation of hydrated electrons via single-visible-photon excitation of localized surface plasmon resonances (LSPRs) of supported sub-3 nm copper nanoparticles in contact with water. Only excitations at the LSPR maximum resulted in the formation of hydrated electrons, suggesting that plasmon... (More)

The reactivity of the hydrated electrons was confirmed via proton reduction and concomitant H
