N2 - Layered Ruddlesden-Popper (RP) neodymium nickelate oxide, Nd2NiO4+δ, is considered a potential cathode material in solid oxide fuel cells. In this study, the equilibrium properties of NNO were investigated by using quasi-equilibrium oxygen release to contract the isothermal equilibrium diagram “lg pO2 – (4+δ) – T”. Furthermore, the kinetic properties of NNO were studied by oxygen partial pressure relaxation to determine the equilibrium oxygen exchange rate (R0), chemical diffusion coefficient in oxide (Dchem), and surface exchange rate constant (kchem). The Brønsted-Evans-Polanyi-type linear free energy relationship was shown to exist between the standard Gibbs energy of the reaction and the activation energy of the reaction rate constant.
