The nanoscopic structure of Pt-water electrified interface under bias revealed — •Clotilde Cucinotta — Imperial College London

In this talk I will introduce some issues connected with the simulation of electrified interfaces at the nanoscale focusing in particular on modelling the effect of an applied potential to an EC cell. I will present some recent progress in the simulation of the double layer of the fundamental Pt-water interface and its response to changes of potential applied to the cell. I will show that the metal/surface charging cannot be described using a traditional simple capacitor model and that the double layer nanoscopic structure, mass density and charge distribution, strongly depend on the applied potential.
