Resumen:
Pure-phase Sr2MgMoO6 (SMMO) nanopowder was obtained by combustion synthesis (CS) from an aqueous solution of metal nitrates, glycine and ammonium nitrate and subsequent treatment in air at 900 1C. The morphological and structural characterization was performed by X-Ray diffraction (XRD), N2 physisorption and scanning electron microscopy (SEM). This nanostructured powder presents average crystallite size of 150 nm and a sponge-like morphology composed of highly interconnected crystallites and an effective specific area of 5.6 m2 /g. EIS measurements indicate ASR values as low as 0.07 Ω cm2 at 800 1C.
