Abstract: Nickel-iron layered double hydroxide (NiFe LDH) was used as a non-precious metal OER catalyst, and its catalytic performance was improved by optimizing composition, structure and reaction environment. First, by adjusting the Ni/Fe molar ratio (4 : 1), the overpotential ( η10 ) of the catalyst was reduced to 1.51 V (vs. RHE), the current density was increased to 61.3 mA·cm -2 , and the utilization of active sites was optimized. Secondly, by controlling the hydrothermal treatment temperature (160 °C) to adjust the thickness of the nanosheet to 7.2 nm, η10 was further reduced to 1.50 V, the current density was increased to 61 mA·cm -2 , and the electron transfer capacity was improved. Finally, the electrolyte pH (pH=13) was optimized to further reduce the η10 of the catalyst in a high alkaline environment to 1.49 V, showing the best OER activity. The optimized NiFe LDH was applied to the actual water electrolysis hydrogen production system. Under the conditions of 60 °C and 100 mA·cm -2 , the operating voltage was reduced to 1.62 V, which was significantly lower than that of the unoptimized catalyst 70 V). In the 100 h constant current test, only 20 mV of voltage decay occurred, indicating its excellent stability.
