Structural characterization of high n Ruddlesden-Popper nickelates under operating conditions of solid oxide cell oxygen electrode

This proposal aims at obtaining precise structural and microstructural models of two complex Ruddlesden-Popper (RP) oxides of different dimensionality La3Ni2O7±δ and Ln4Ni3O10±δ (Ln = La, Pr), studied for solid oxide fuel and electrolysis cell (SOFC & SOEC) applications, by high resolution powder synchrotron X-Ray diffraction at temperatures close to the operating conditions of the cells (between RT and 950°C under air).
