摘要	To deal with energy and environmental issues, it is necessary to exploit efficient and stable electrocatalysts for the generation of clean hydrogen. Herein, we describe the synthesis of bimetallic Fe/Ni alloy encapsulated by amorphous carbon shells via a facile annealing strategy for electrocatalytic oxygen evolution reaction (OER). The ferric nickel tartrate annealed at 800 degrees C (Ni3Fe1Ox@C-800) exhibits a low OER overpotential of 264 mV at 10 mA cm-2 and good stability in alkaline media. Compared with monometallic counterpart, bimetallic Ni3Fe-based nanocomposites show lower OER barrier (ca. 324 kJ mol-1) due to a cooperation mechanism between Ni and Fe sites in promoting electrocatalytic water oxidation. Compared with those annealed at other temperatures, the enhanced OER performance of Ni3Fe1Ox@C-800 can be ascribed to the large electrochemical surface area for exposing more active sites, smaller charge transfer, and better intrinsic activity of Ni3Febased sites.
