a Polarization curves. RHE reversible hydrogen electrode. b Overpotentials (η10) of RuO2 and LixRuO2 at 10 mA cm−2. The error bars represent the deviation from the overpotentials in (a). c Tafel plots. d Chronopotentiometry curve of Li0.52RuO2 and RuO2 at a current density of 10 mA cm−2. e Percentage of Ru dissolved from RuO2 and Li0.52RuO2 after electrocatalysis for different reaction times. f Comparison of the overpotential required to achieve a 10 mA cm−2 cathodic current density and chronopotentiometry durability at 10 mA cm−2 in acidic media for various RuO2-based electrocatalysts14,17,23,25,40,41,42,43.
