Hot hole direct photoelectrochemistry of Au NPs: Interband versus Intraband hot carriers

Optically-excited gold nanoparticles (Au NPs) generate plasmon oscillations that induce hot charge carriers by non-radiative decay. These hot charge carriers are to improve the energy conversion efficiency of photochemical and photoelectrochemical reactions. Depending on the mode of excitation (i.e., interband or intraband), the energy of the hot electrons and hot holes vary significantly. Although, both interband and intraband hot carriers …
