One-step hydrothermal synthesis of a Ni₃S₂-FeMoO₄ nanowire-nanosheet heterostructure array for synergistically boosted oxygen evolution reaction.

ABSTRACT: A key factor for boosting oxygen evolution reaction (OER) is the design of heterostructures with steerable defects and interfaces, which can optimize the surface electronic structures and achieve efficient water splitting to produce hydrogen fuel. Herein, we propose a novel one-step hydrothermal approach to fabricate hierarchical Ni₃S₂ nanowires with an S-doped FeMoO₄ nanosheet heterostructure array in situ on Ni-Fe foam (NFF) as a self-standing electrode for synergistically boosted OER. The metalloid Ni₃S₂ nanowires with good conductivity support the FeMoO₄ nanosheets and act as high-speed paths for the charge transfer. Numerous ultrathin S-doped FeMoO₄ nanosheets are uniformly distributed on each Ni₃
