a In situ XRD patterns, b in situ Raman spectra and c corresponding contour plots, d in situ ATR–IR spectra of F–RuO2/FC. e DEMS signals of 32O2, 34O2, and 36O2 from the gaseous products for 18O–labeled F–RuO2/FC catalysts in H216O aqueous H2SO4 electrolyte during three times of LSV cycles. f Schematic illustration of the mechanism transformation from lattice oxygen mechanism (LOM) to adsorption evolution mechanism (AEM) caused by F–mediated symmetry breaking on RuO2. Source data for this figure are provided as a Source Data file.
