Fig. 2: Characterization of Ir1/NC, Co1/NC and Rh/C.
From: Kinetically restrained oxygen reduction to hydrogen peroxide with nearly 100% selectivity
a Atomic-resolution HAADF-STEM images of Ir1/NC. b Ir L-edge XANES spectra of Ir1/NC, Ir foil, and IrO2. c FT-EXAFS spectra at the Ir L-edges of Ir1/NC, Ir foil, and IrO2. d Atomic-resolution HAADF-STEM image of Co1/NC. e Co K-edge XANES spectra of Co1/NC, Co foil, and CoO. f FT-EXAFS spectra at the Co K-edges of Co1/NC, Co foil, and CoO. g Schematic illustration of Rh/C synthesized without urea and the HAADF-STEM image with energy-dispersive X-ray elemental mapping of Rh/C. h XRD patterns of Rh1/NC and Rh/C. i N2 adsorption-desorption isotherms of Rh1/NC and Rh/C. Experiment (Fig. 2a, d, g) was repeated 3 times independently with similar results.
