Fig. 4: Synthesis of MnFeCoCuZn-HESACs.

From: A templating approach with phase change to tailored coordination of single- and multiple-atom catalysts

Fig. 4

a HAADF-STEM, b TEM image of HESACs and c corresponding EDS mappings of N, Cl, Mn, Fe, Co, Cu and Zn (The scale bar is 400 nm). d FT-EXAFS spectra of the metals in HESACs. e HAADF-STEM images of Fe SACs synthesized via an alternate component (The scale bar is 2 nm). The inset images correspond to the following replacement components: sucrose, citric acid, melamine, urea, potassium chloride, and commercial table salt, respectively. Gray sphere: C; purple sphere: O, blue sphere: N; orange sphere: K; yellow sphere: Cl.
