Boosting the Oxygen Evolution Reaction by Controllably Constructing FeNi₃/C Nanorods.

ABSTRACT: Transition bimetallic alloy-based catalysts are regarded as attractive alternatives for the oxygen evolution reaction (OER), attributed to their competitive economics, high conductivity and intrinsic properties. Herein, we prepared FeNi₃/C nanorods with largely improved catalytic OER activity by combining hydrothermal reaction and thermal annealing treatment. The temperature effect on the crystal structure and chemical composition of the FeNi₃/C nanorods was revealed, and the enhanced catalytic performance of FeNi₃/C with an annealing temperature of 400 °C was confirmed by several electrochemical tests. The outstanding catalytic performance was assigned to the formation of bimetallic alloys/carbon composites. The FeNi₃/C nanorods showed an overpo
