A series of nanostructured La_1-xNd_xCo_0.3Fe_0.7O₃ perovskite-type (x ranging from 0 to 1) were prepared using the co-precipitation method. CO gas sensing properties of La_1-xNd_xCo_0.3Fe_0.7O₃ sensors were performed. La_0.7Nd_0.3Co_0.3Fe_0.7O₃ sensor showed the highest response at 250 °C (S=52.8).
