Abstract

Abstract: A detailed understanding of the dissociation of O2 molecules on metal surfaces induced by various excitation sources, electrons/holes, light, and localized surface plasmons, is crucial not only for controlling the reactivity of oxidation reactions but also for developing various oxidation catalysts. The necessity of mechanistic studies at the single‐molecule level is increasingly important for understanding interfacial interactions between O2 molecules and metal surfaces and to improve the reaction efficiency. We review single‐molecule studies of O2 dissociation on Ag(110) induced by various excitation sources using a scanning tunneling microscope (STM). The comprehensive studies based on the STM and density functional theory calculations provide fundamental insights into the excitation pathway for the dissociation reaction. Abstract : The dissociation of O2 on metal surfaces has been widely studied as a key reaction in oxidation. This account highlights single‐molecule studies of the dissociation of O2 on Ag induced by various excitation sources such as electrons/holes, light, and localized surface plasmons by using a scanning tunneling microscope, which reveals efficient reaction pathways and provides a deeper understating for the excitation mechanisms in terms of interfacial interaction between the molecule and metal surface.
