Synchrotron-based WAXS 2D images and Q values of a CNIrSA and b MCIrSA. No peak for any particulate distribution was observed. c HR-TEM image and respective of MCIrSA showing amorphous structure MCIrSA. d AC-HAADF STEM image of MCIrSA, arrows and circles pointing to bright spots for Ir single atom. e EELS elemental mapping for N (orange), O (blue), and Ir (pink). f Normalized XANES spectra of IrCl3 (black), IrO2 (green), CNIrSA (violet) and MCIrSA (red). g FT-EXAFS spectra of Ir metal, IrO2 NPs, CNIrSA and MCIrSA (solid line: experimental data, dots: fit). WT map of h MCIrSA. i Ir foil. j IrO2 NPs.
