金属光催化制氢Plasmonic-metalnanostructuresforefficient1 NATURE MATERIALS | VOL 10 | DECEMBER 2021 | 911 Plasmonic metallic nanostructures are characterized by their strong interaction with resonant photons through an excitation of surface plasmon resonance (SPR). SPR can be described as the resonant photon-induced collective oscillation of valence electrons, estab-lished when the frequency of photons matches the natural fre-quency of surface electrons
