a LSV polarization curves, b corresponding Tafel plots, c EIS spectrums of MA-LTMO-CO2Ls and Co3O4. d Double layer capacitance (Cdl) of MA-LTMO-CO2Ls and Co3O4, derived from linear regression fits with R2 > 0.995. e Chronopotentiometry curve (10 mA cm–2, 200 h, without iR compensation) for MA-S-LTMO-CO2L, with the arrow marking the electrolyte replenishment (inset: LSV polarization curves of MA-S-LTMO-CO2L before and after long-term stability). And f the overpotentials at a current density of 10 mA cm–2 for MA-LTMO-CO2Ls and other reported TM-based OER catalysts (Supplementary Table 3).
