Plasmon-enhanced chemical reactions

The emerging field of plasmonics with the capability to guide and localize light in the nanoscale regime has enabled technologies that can efficiently harvest and utilize solar energy for chemical processes. In this review, recent advances at the intersection of plasmonics and chemical reactions are surveyed. The origins of plasmonic enhancements in chemical reactions will be first discussed. The applications of localized plasmons in various chemical reactions, including photodecomposition of organic pollutants, solar water splitting, and organic synthesis, will then be summarized. We will also discuss the challenges that can expedite the progress of plasmon-enhanced chemical reactions.
