Overview of the functionality of different electrocatalysts for GEOR from the literature and from the present work. (a) Current density in alkaline media. Data adapted from: ref (5) for polycrystalline Pt (Poly Pt) and Au (Poly Au); ref (6) for NiOx, FeOx, CoOx, and MnOx. Data for Pt/C are from the present study. (b) Faradaic selectivity toward C3 products. Data for Pt were averaged from refs (5), (7), and (8) at a potential between 0.5 and 0.9 VRHE; data for NiOx were averaged from refs (6) and (9) at a potential above 1.3 VRHE.
