图8 CoFeAl-FeOOH-6和CoFeAl LDH的催化性能

Fig.8 Catalytic performance of the CoFeAl-FeOOH-6 and the CoFeAl LDH was measured by the two-electrode method, respectively (a) LSV measurement at a scan rate of 2 mV·s-1 without iR compensation, (b) Nyquist plots measured at 1.352 V (vs. RHE), (c) Multistep chronopotentiometry response without iR compensation with the current density of 10, 30, 75, 100 and 150 mA·cm-2, (d) Chronopotentiometric curves measured at the current density of 100 mA·cm-2
