Fig. 2

a Aberration-corrected HAADF-STEM image of PCN/Ru nanosheets. The bright dots are Ru single atoms on PCN nanosheets. b Normalized XANES spectra at the Ru K-edge of PCN/Ru nanosheets. Inset: absorption edge positions of Ru XANES spectra. c Fourier transforms of EXAFS spectra at the Ru K-edge. d Fitting of Ru coordination environment in PCN/Ru. Inset: Theoretical model of Ru-N4 configuration. e XANES spectra at the N K-edge of PCN/Ru nanosheets. f EIS spectra of BCN, PCN, and PCN/Ru. WT-EXAFS of the Ru K-edge of g Ru foil, h RuO2, and i PCN/Ru.
