摘要：The nano-sized (La0.8Sr0.2)2FeNiO6-Δ(LSFN) double perovskite powder without impurity phase was successfully prepared using the Pechini method. The result demonstrated that the electrode sensing properties to NO2were affected by the sintering temperature. The sensor with 1300°C-sintered LSFN sensing electrode exhibited the highest NO2sensitivity.
