Abstract

Understanding the structures of electrochemical interfaces at the atomic level is key to developing efficient electrochemical cells for energy storage and conversion. Spectro- scopic techniques have been widely used to investigate the structures and vibrational properties of the interfaces. The interpretation of these spectra is however not straight- forward. In this work, density functional theory based molecular dynamics simulations were performed to study the vibrational properties of the Pt(111)- and Au(111)-water interfaces. It was found that specific adsorption of some surface water on Pt(111) leads to partial charge transfer to the metal, and strong hydrogen bonding with neighboring water, which resolves the interpretation of the elusive O-H stretching peak around 3000 cm−1 observed in some experiments.
