a Operando Raman spectra of MV-S/Co(OH)2/MI during OER electrocatalysis. b Co K-edge XANES profiles, and c Fourier transform EXAFS of MV-S/Co(OH)2/MI, MV-S/Co(OH)2, MV-Co(OH)2/MI, and Co(OH)2 after OER. d Potential-dependent operando ATR-SEIRAS of MV-S/Co(OH)2/MI. e DEMS signals of 36O2 products for 18O-surface-labeled MV-S/Co(OH)2/MI and Co(OH)2 tested in the electrolyte using H216O as solvent. f Polarization curves of MV-S/Co(OH)2/MI with or without TMA+. g Polarization curves of MV-S/Co(OH)2/MI in the electrolytes utilizing H2O and D2O as solvents, respectively. Inset shows the dependence of KIEs value on overpotential. Source data are provided as a Source Data file.
