On the work function changes and other properties of the gas-exposed electrode surface in the NEMCA effect

Topics in Catalysis Aims and scope Submit manuscript

A simple model is developed to describe the backspillover of ionic species at the solid/gas interface as observed in non-Faradaic electrochemical modification of catalytic activity (NEMCA) systems. This model predicts a linear relationship between work function changes and changes in the potential difference at the metal/solid electrolyte interface, as observed experimentally. It also predicts a linear dependence of the surface coverage by ionic species on the potential difference at the metal/solid electrolyte interface, and a linear dependence of the binding energy of adsorbed species on the work function of the gas-exposed catalyst surface.
