From: Identifying and tuning coordinated water molecules for efficient electrocatalytic water oxidation
a LSV polarization curves of Ni-tPBA0~3/CP at 5 mV/s with iR-correction (the series resistance is 2.4, 2.3, 2.4 and 2.4 Ω for Ni-tPBA0~3/CP, respectively). The inset is the illustration of the electron transfer and catalysis process. b Tafel plots, (c) Cdl values, and d electrochemical impedance spectra at an overpotential of 300 mV. e Stability test for Ni-tPBA3/CP in H-type cell with anion exchange membrane at the constant current density from 10~400 mA cm–2 (without iR-correction).
