Figure 3

(a) CV curves of PCN-226(Co) in 0.1 M KOH solution saturated by N2 and O2, respectively. (b) LSV curves, (c) electron transfer numbers (n), and (d) Tafel plots of PCN-226(Co), PCN-221(Co), PCN-222(Co), and Pt/C. (e) Durability test at 0.46 V (vs RHE) and 1600 rpm in O2-saturated 0.1 M KOH solution, where j0 is the initial current. It shows PCN-226(Co) has the lowest current loss (18%), followed by Pt/C (20%), PCN-221(Co) (48%), and PCN-222(Co) (50%). The MOFs were mixed with 50% carbon black.
