摘要：

Ni/NiFe2O4 nanorods encapsulated in onion-like N-doped carbon (ONC) nanolayers was prepared by the pyrolysis of NiFe-based coordination polymer precursor under N-2 atmosphere. Compared with Ni@ONC, NiFe2O4, and commercial RuO2 electrocatalysts, benefiting by the promoted electronic conductivity and enlarged electrochemical surface area (0.149 mF) from synergistic effects between the ONC nanolayers and encapsulated Ni/NiFe2O4 heterostructure, the as-prepared Ni/NiFe2O4@ONC hybrid nanorod exhibits extraordinary electrocatalytic activity towards oxygen evolution reaction (OER) with an overpotential of similar to 299 mV at 10 mA.cm(-2) and a Tafel slope of 73 mV.dec(-1).
