Plasmon-enhanced electrochemistry: Fundamentals and potential applications

Plasmon-enhanced electrochemistry is an interdisciplinary field integrating photonic excitation, plasmonic nanostructures, and applied electrochemical potentials. Building upon the established applications of plasmonic phenomena in photocatalysis and electrocatalysis, plasmon-enhanced electrochemistry has emerged as a novel research frontier attracting significant scientific attention. While numerous systematic investigations have been conducted to elucidate both theoretical frameworks and experimental manifestations of plasmon-enhanced electrochemical systems, fundamental understanding of their underlying physicochemical mechanisms remains incomplete. This review aims to establish a mechanistic foundation for plasmon-enhanced electrochemical processes, and propose strategic perspectives for harnessing plasmon-enhanced electrochemical principles in reaction engineering. Such advancements could ultimately enable innovative approaches to energy conversion technologies.
