Abstract: This paper presents results of research aimed at elucidating factors controlling mobility and reactivity of the surface and bulk oxygen of complex perovskite-like AnBmOz oxides (manganites, ferrites, cobaltites, nickelates of La/Sr) and their nanocomposites with fluorite-like oxides (doped ceria or zirconia) as related to their performance in the intermediate temperature solid oxide fuel cells (IT SOFC) cathodes and oxygen separation membranes. Real/defect structure and surface properties of these materials as a function of both composition, preparation route and sintering temperature were studied by combination of TEM with EDX, XRD, EXAFS, UV-Vis and XPS methods. Lattice oxygen mobility, strength of oxygen species bonding with the surface sites and their reactivity for both dispersed and dense materials were estimated by oxygen isotope exchange, temperature-programmed desorption and reduction by H2 and CH4. Coefficients of oxygen diffusion in dense materials were estimated by analysis of dynamics of the oxygen loss monitored by measurements of the weight loss or conductivity relaxations. For analysis of atomic-scale factors controlling oxygen bonding strength and mobility, quantum-chemical approaches including the Density Functional Theory (DFT) in spin-polarized SLDA approximation and semiempirical Interacting Bonds Method were applied.
