Fig. 1. Electrostatic conditions around a supported Pt nanoparticle in electrochemical environment.
a Schematic cell used to derive Eq. (1) with Pt/Support electrode, electrolyte, and reference electrode (Ref). For ease of derivation and without loss of generality, the reference electrode metal M is considered to form a dense layer on a substrate of the same support material. The inner electrostatic potentials of different phases i are denoted by Φi. b Interface charging at the Pt/Support electrode in a strongly screening electrolyte, i.e. for wdl ≪ dPt, at the PZC EqPt=0Pt∕Sup, i.e. for zero charge on the external Pt nanoparticle surface in contact with the electrolyte. Negative ions of the electrolyte are depicted by circles with negative signs inside. EMSI charge transfer is confined to the direct support–Pt interface, and it closes the “gap” in the electrochemical double layer of the support at the place of the Pt nanoparticle. The external Pt nanoparticle surface is screened by the strong electrolyte from the support interface, and thus its PZC is the same as for an unsupported Pt electrode.
