Nanoarchitectonics of Fe-Doped Ni₃S₂ Arrays on Ni Foam from MOF Precursors for Promoted Oxygen Evolution Reaction Activity.

ABSTRACT: Oxygen evolution reaction (OER) is a critical half-reaction in electrochemical overall water splitting and metal-air battery fields; however, the exploitation of the high activity of non-noble metal electrocatalysts to promote the intrinsic slow kinetics of OER is a vital and urgent research topic. Herein, Fe-doped Ni₃S₂ arrays were derived from MOF precursors and directly grown on nickel foam via the traditional solvothermal way. The arrays integrated into nickel foam can be used as self-supported electrodes directly without any adhesive. Due to the synergistic effect of Fe and Ni elements in the Ni₃S₂ structure, the optimized Fe_2.3%-Ni₃S₂/NF electrode delivers excellent OER activity in an alkaline medium. The op
