Fig. 4: HR-TEM images and EDS Mapping of Ni and Co of LNCO samples.

From: Highly active and thermostable submonolayer La(NiCo)OΔ catalyst stabilized by a perovskite LaCrO3 support

Fig. 4

a LNCO-F, b LNCO-R, and c LNCO-U100 represent fresh, H2-reduced, and used after 100 h time on stream LaNi0.05Co0.05Cr0.9O3 samples, respectively. The 1st row: HR-TEM images, the 2nd row: magnified HR-TEM images corresponding to the yellow squares in the 1st row, the 3rd row: EDS Mapping of Ni corresponding to the HR-TEM images in the 1st row, and the 4th row: EDS Mapping of Co corresponding to the HR-TEM images in the 1st row. The regions marked by yellow squares in (b, c) are Ni-rich and Co-rich.
