Figure 14
SEM images after reduction in humidified H2 of the NdCo sample at 575 °C. The image on the right is a detail of the image on the left (green box) at higher magnification. Uniformly distributed exsolved nanoparticles up to 50 nm in size decorated the perovskite surface. There were more particles and they were smaller than for Nd0.9 (diameters around 200 nm). Similar to Fig. 10, there is a crumbled piece of the perovskite visible in the lower right corner of the magnified area. |
