a Ambient polarization curves (with iR correction) in natural seawter. b Δη/Δlog | j| ratios of NCP-based cathodes under a series of j intervals. c Tafel slopes in the varied situations. d Visual comparisons of Cdl, mass activity, and η for various cathodes. e Chronopotentiometry curves for various cathodes and the corresponding ΔE. f Pictures of various cathodes after the 10 h of eNSR. Scale bar: 0.5 cm. g ACa&Mg values for various cathodes after the long-term eNSR testing. For f from the left to the right are: NCP/PC, NCP/NF, NCP/TM, NCP/CC, NCP/GF, and NCP/CP.
