The here discussed method exploits the relationship between nanoparticle architecture and electrochemical activity and is applied to study the catalytic properties of MgO(100)-supported Pt nanosystems undergoing solid-solid and solid-liquid transitions. We observe that a major increment in the activity is associated to the reconstruction of the interface layers, supporting the need for a full geometrical characterisation of such structures also when in-operando.Chemistry, PhysicalPhysics, Atomic, Molecular & ChemicalChemistryPhysicselectrocatalysisgeneralised coordination numbermolecular dynamicsplatinumsupported nanoparticlepredictionmetalssitesCorrelating Oxygen Reduction Reaction Activity and Structural Rearrangements in MgO-Supported Platinum Nanoparticlestext::journal::journal article::research article
