Fig. 3: Synthesis of different SACs.

a Schematic diagram of a SAC library. The orange, blue and purple boxes represent the main group, transition and rare earth metals, respectively. b HAADF-STEM images of 24 SACs. The scale bar is 5 nm. c The FT-EXAFS analysis for M1CNCl fits in R space. d Photographs of batches containing 10 g of Mn, Fe, Co, Ni, Cu and 5 g of Ca, Cr, Zn, Ga, La, Tb SACs.
