Fig. 1: Synthesis and characterization of Rh1/NC.
From: Kinetically restrained oxygen reduction to hydrogen peroxide with nearly 100% selectivity
a Schematic of the synthesis process of Rh1/NC. TEM b and SEM c images of Rh1/NC. d HAADF-STEM image and the corresponding energy-dispersive X-ray elemental mapping of Rh1/NC. e, f Atomic-resolution HAADF-STEM images of Rh1/NC. g FT-EXAFS spectra at the Rh K-edges of Rh1/NC Rh foil and Rh2O3. Insert: structure of RhN4 for EXAFS fitting and DFT calculation. Experiment (Fig. 1b–f) was repeated 3 times independently with similar results.
