Abstract
In this work, we successfully synthesized NiFe-LDH@RGO composites through a facile hydrothermal method. Therein, multiple composite samples with different mass ratio of NiFe-LDH and RGO were synthesized in order to improve its OER activity. Structural characterizations of these samples were investigated by XRD, Raman, SEM, TEM and HRTEM, and it shows that NiFe-LDH quantum dots with the average size of 5 nm dotted on the RGO sheets uniformly without any agglomeration. The OER tests show that, the NiFe-LDH@RGO = 1/1 sample can be used as a good OER catalyst with the overpotential of 313 mV (vs. RHE) at the current density of 10 mA cm−2 and Tafel slope of 35.1 mV dec−1.
