Preparation of (La _0.8Sr _0.2) ₂FeNiO _6-Δ Nanopowder by Pechini Method and Its Sensitivity to NO ₂

摘要

The nano-sized (La_(0.8)Sr_(0.2))_(2)FeNiO_(6-Δ)(LSFN) double perovskite powder without impurity phase was successfully prepared using the Pechini method. The result demonstrated that the electrode sensing properties to NO_(2)were affected by the sintering temperature. The sensor with 1300°C-sintered LSFN sensing electrode exhibited the highest NO_(2)sensitivity.
