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 5â¯nm dotted on the RGO sheets uniformly without any agglomeration. The OER tests show that, the NiFe-LDH@RGOâ¯=â¯1/1 sample can be used as a good OER catalyst with the overpotential of 313â¯mV (vs. RHE) at the current density of 10â¯mAâ¯cmâ2 and Tafel slope of 35.1â¯mVâ¯decâ1.
