文摘

NiFe-LDH/NrGO catalyst was obtained via a one pot method by solvothermal reaction. ORR and OER activities of NiFe-LDH/NrGO in alkaline media were firstly investigated. NiFe-LDH/NrGO gives a superior ORR activity and stability involving the 4e pathway. NiFe-LDH/NrGO also shows better OER activity with a 250 mV onset overpotential.
