Abstract
The role of the discreteness of the charges at ITIES has recently been revisited within the framework of the so-called "Discrete Helmholtz" model. The main conclusion of this model is that the potential drop across an ITIES takes place over a bilayer of correlated ions rather than across two back-to-back diffuse layers as suggested by the Gouy Chapman approach. The experimental signatures from Surface Second Harmonic Generation (SSHG) and electrocapillary measurements are a constant capacitance and a linear relationship between surface charges and applied potential. We shall here discuss polarisation at ITIES and compare the different models. We shall also discuss how the interfacial polarisation acts as a driving force for potential dependant electrochemical reactions such as ion transfer and electron transfer.In the second part of the presentation, we shall discuss water splitting reactions at ITIES using redox photo-electrocatalysis. We shall discuss the different reactions leading to hydrogen evolution and present some very recent data on oxygen evolution.Finally, we shall discuss the feasibility of batch water splitting at ITIES as an industrial process.
