Based on layered double hydroxides, a series of binary NiFe-LDH catalysts were prepared by a simple hydrothermal synthesis method. The crystal structure, morphology and oxygen evolution activity of the catalysts were tested by XRD, SEM and polarization curve. Compared with Ni ( OH ) 2 , NiFe-LDH-1 exhibited the best OER activity with overpotentials of 218 mV and 264 mV at 10 mA·cm-2 and 100 mA·cm-2 , and a Tafel slope of 36.3 mV·dec-1 . Meanwhile, NiFe-LDH-1 exhibited excellent long-term stability.
