摘要:
Herein, a simple two-step synthetic method was developed for the synthesis of NiFe(2)O(4) nano-microrods supported on Ketjenblack carbon (NiFe(2)O(4)/KB). A sodium tartrate-assisted hydrothermal method was employed for the synthesis of a NiFe-MOF/KB precursor, which was then pyrolyzed under N(2) at 500 °C to yield NiFe(2)O(4)/KB. Benefiting from the presence of high-valence Ni(3+) and Fe(3+), high conductivity, and a large electrochemically active surface area, NiFe(2)O(4)/KB delivered outstanding OER electrocatalytic performance under alkalin...
