Plasmon-mediated chemical reaction (PMCR) is an emerging field of research and development in which chemical reactions are enabled by plasmonic nanomaterials that function as mediators to redistribute and convert photon energy into localized photon, electron, and/or thermal energies. Multiple recent reports have made it a promising approach for facilitating light-driven chemical reactions by utilizing solar energy. Moreover, based on unique properties of plasmonic nanomaterials, PMCR exhibits differences from and potential advantages over traditional thermochemistry, photochemistry, and photocatalysis. However, PMCR still faces challenges such as a far from complete understanding of its operating mechanisms, which contributes to current limitations in reaction efficiency and selectivity. This Perspective aims to be a relatively complete current physicochemical description of PMCR and provides a comprehensive comparison with other reaction systems as well as identifying unique features. Challenges and opportunities are discussed to guide future directions and stimulate the interest of a broad range of scientists with varying backgrounds.
