Abstract:

Plasmonic nanoparticles have been explored for hot carrier generation for “green” photocatalysis through excitation of localized surface plasmon resonance (LSPR). In contrast, carrier generation through excitation of interband transitions remains a less explored and underestimated pathway. In this study, photoinduced oxidative etching of gold nanoparticles with FeC13 was investigated as a model reaction in order to elucidate the photocatalytic activities originated from these two optical transitions. Interband transitions generate hot carriers more efficiently, and those carriers exhibit higher reactivity as compared to those generated by LSPR. To expand the application of this gold nanoparticle photo catalyst to organic synthesis, a cyclization reaction of alkynylphenols was developed.
