Porous iron–nickel hydroxyphosphate and iron–cobalt hydroxyphosphate electrodes are prepared byone-step electrodeposition method. The as-prepared iron–nickel hydroxyphosphate and iron–cobalthydroxyphosphate electrodes show excellent performance for water splitting with high catalytic activitytowards the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), with a loweroverpotential of 220 and 235 mV for the OER and 145 and 160 mV for the HER, respectively. Moreover,two-electrode electrolyzer using iron-nickel hydroxyphosphate as both the anode and cathode requires acell voltage of 1.65 V while iron–cobalt hydroxyphosphate requires cell voltage of 1.67 V to gain currentdensity of 10 mA cm 2.
