摘要：
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/cm(2) 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/cm(2) was decreased to 1. 515 V vs. RHE.
