Figure S1: ORR activity of Pt/C catalyst modified with [BMIM][beti]. A) ORR polarization curves obtained in RDE measurements at room temperature in oxygen saturated 0.1 M HClO4 and 1600 rpm at a catalyst loading of 20 µgPt cm-2. B) ORR polarization curves obtained in GDE measurements at room temperature in oxygen atmosphere in 2 M HClO4 at a catalyst loading of 100 µgPt cm-2.
