摘要： Plasmon-excitation-mediated chemistry, which is a rapidly growing field, is founded on a simple principle: the excitation of the localized surface plasmon resonance (LSPR) of metal nanoparticles triggers chemical reactions on the surfaces of the nanoparticles. Early examples of plasmon-excitation-driven nanoparticle synthesis and hot-electron-driven chemical reactions induced by ultrashort pulse excitation of metal nanoparticles can be thought of as precursors to the findings of direct photocatalysis by plasmonic nanoparticles, which is the focus of this Viewpoint. The field in its current state was, in large part, invigorated by a 2011 paper, which showed that the excitation of the LSPR of Ag nanoparticles by continuous-wave (CW), visible-frequency light triggered the dissociation of adsorbed O2. The O· atoms thus produced were utilized for industrially relevant oxidation reactions such as those of propylene and ethylene, which would have otherwise required high-temperature and -pressure conditions to proceed at appreciable rates. In the absence of visible-light excitation, the bond dissociation and oxidation reactions proceeded at appreciably low rates, which indicated that plasmonic excitation enhanced the rates of these chemical reactions. The phenomenon is, therefore, termed as plasmonic catalysis or plasmonic photocatalysis.
