Adapted and reprinted with permission from ref. 22. b RRDE polarization plots for an Fe-based SAC (red trace) where the ORR E1/2 was measured to be 0.88 V vs. RHE as compared to a Pt/C reference (gray trace) with E1/2 of 0.87 V vs. RHE. Adapted and reprinted with permission from ref. 27. c Hydrogen fuel cell performance with the same Fe-based SAC where a current density of 145 mA/cm2 was achieved at 0.8 V vs. RHE. Adapted and reprinted with permission from ref. 27. d Electrocatalytic OER performance for a Ru-SAC (red trace) compared with commercial RuO2/C reference (blue trace) in 0.5 M H2SO4.
