Fig. 3 — a Chronoamperometric curves of Ru/TiO_x, annealed RuO_x/TiO₂, com. RuO₂/TiO₂ and com. IrO₂/TiO₂ for OER at 100 mA cm⁻². The chronoamperometric curves are not iR compensated. Mass loadings of noble metals are 0.0715, 0.0867, 0.0992, and 0.1135 mg cm⁻² for Ru/TiO_x, annealed RuO_x/TiO₂, com. RuO₂/TiO₂ and com. IrO₂/TiO₂, respectively. b Chronoamperometric curves of Ru/TiO_x for OER at 10 mA cm^-2. c Comparison of the overpotential and stability time of Ru/TiO_x with state-of-the-art OER electrocatalysts in acidic media. d Inductively coupled plasma-mass spectrometry (ICP-MS) analysis for dissolved Ru ions in post chronopotentiometry electrolyte and Ru mass percentage retained in Ru/TiO_x, annealed RuO_x/TiO₂ and com. RuO₂/TiO₂ catalyst after the chronoamperometric test.
