Synthesis of SmBaCo2O6−δ powder by the combustion process using Co3O4 as precursor

New Chemical Systems for Solid Oxide Fuel Cells

“…A SmBaCo 2 O 5+δ cathode on SDC and LSGM electrolytes gave polarization resistances of 0.098 and 0.054 Ω cm 2 , respectively, at 750 °C, with maximum power densities for a single cell reaching 641 and 777 mW cm −2 , respectively, at 800 °C. The low temperature synthesis of this SmBaCo 2 O 5+δ material has been reported by Sun et al, who successfully synthesized it by the citric acid−nitrate gel combustion process at temperatures as low as 900 °C for 4 h, using undissolved and relatively inexpensive Co 3 O 4 as a starting material. Through such low temperature synthesis routes, control of particle size and hence cathode morphology can be achieved, hence offering further advances.…”

“…Therefore, the further research on the hightemperature properties is required. As a new family of cathode materials with double-perovskite structure, LnBCO cathodes with a single lanthanide-ion have been recently reported, such as PrBCO [21,22], NdBCO [23], SmBCO [24,25], GdBCO [26][27][28] and YBCO [29]. And these double-perovskite cathodes have showed good electrical conductivity and high-electrocatalytic activity for the oxygen-reduction reaction.…”

Conducting solids

“…Promising results have also been reported for analogous materials with Sm as the lanthanide. Strategies for improving the synthesis of these materials have also been widely examined, and in this respect Sun et al 102 have reported the low temperature (900 1C for 4 h) synthesis of SmBaCo 2 O 5+d . The synthesis route employed the citric acid-nitrate gel combustion process, using undissolved and relatively inexpensive Co 3 O 4 as a starting material.…”
