Abstract

The performance and potential application of the cubic members of the La(4)Sr(n-4)TinO(3n+2) series of compounds, i.e. n >= 42, prepared by solid state reaction are discussed. Although these phases can be indexed as cubic perovskites by X-ray diffraction (XRD), there exists some oxygen beyond the ABO(3) stoichiometry accommodated in linear defects reminiscent to the oxygen rich layers in La2Ti2O7. In the present work, we report preliminary fuel cell tests of the n=12,14 and 16 of the La4Srn-4TinO3n+2 series, which reveal moderate responses under hydrogen, but also some promising results implying activation favouring methane oxidation.
