The composites of Ni-Fe layered double hydroxide(LDH) and reduced graphene oxide(rGO) were successfully prepared via a simple exfoliation and electrostatic self-assembly and were used as catalysts for electrooxidation of water(oxygen evolution reaction, OER). The exfoliated Ni-Fe LDH samples exhibited much higher water oxidation activity than the bulk ones. The onset potential was 1.470 V vs. RHE and the potential for maintaining a current density of 10 mA/cm2 was 1.530 V vs. RHE. After being fabricated with rGO, the composite showed better performance for water oxidation than exfoliated Ni-Fe LDH, and the potential for maintaining a current density of 10 mA/cm2 was decreased to 1.515 V vs. RHE.

Key words: Ni-Fe layered double hydroxide(LDH), Oxygen evolution reaction, Water-splitting, Reduced graphene oxide(rGO)
