Fig. 1: Characterization of CuN3-SAzyme.

a Schematic diagram of the synthesis strategy of CuN3-SAzyme and CuN4-SAzyme. 2-methylimidazole: 2-MI. b, c HR-TEM (b) and HAADF-STEM (c) images of CuN3-SAzyme. d Corresponding EDS mapping of CuN3-SAzyme. C, green; N, blue; Cu, red. e Atomic-level HAADF-STEM image of CuN3-SAzyme. f Enlarged HAADF-STEM image of the marked area in (e). g Corresponding surface intensity map of e, the yellow dots are Cu atoms. Three times each morphology characterization was repeated independently with similar results (b–g). Representative images are presented.
