Oxygen evolution reaction (OER) electrocatalysts play a vital role in promoting electrocatalytic water splitting technology, which should cover low cost, superior catalytic activity, and long-term stability to ensure an efficient sustainable process. Herein, we fabricate NiFe-based layered double hydroxide (NiFe-LDH) nanosheet-supported nickel-doped carbon nanofiber (Ni–CNF) as highly oxygen electrocatalyst (Ni–CNF/NiFe-LDH), is synthesized by electrospinning, calcination, hydrothermal methods. The cross-linked network structure of Ni–CNF markedly increases the specific surface area, thereby facilitating exposure active sites. Under synergy conductive ultrathin NiFe-LDH nanosheets, Ni–CNF/NiFe-LDH exhibits outstanding performance OER, requiring only overpotential 262 mV achieve current density 10 mA·cm–2.
