As an efficient non-precious metal catalyst for oxygen evolution reaction in electrochemical and photoelectrochemical water splitting, NiFe LDH/RGO composite is synthesized by a simple solvothermal method in one-pot. NiFe LDHs are uniformly deposited on RGO layers of high electrical conductivity and large surface area. In electrochemical water splitting, NiFe LDH/RGO shows superior OER performance compared to bare NiFe LDH and reference IrO2 with a lower benchmark η10 value of 0.245V. Furthermore, NiFe LDH/RGO substantially increases the performance of a hematite photoanode in photoelectrochemical water oxidation, demonstrating its potential as an OER cocatalyst for photoelectrodes. |
