Fig. 3: Ni 3p, Co 3p, and Cr 3s XPS spectra of LNCO samples.

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

Fig. 3

CrS+1/2 and CrS-1/2 denote intra-atomic multiplet splitting of Cr 3s with the remaining 3s electron coupled parallel and antiparallel to the 3d electrons, respectively. LNCO-F, LNCO-R, and LNCO-U100 represent fresh, H2-reduced, and used after 100 h time on stream LaNi0.05Co0.05Cr0.9O3 samples, respectively.
