Here, controlling the 3-D morphology of nanocatalysts is one of the underexplored but important approaches for improving the sluggish kinetics of oxygen evolution reaction (OER) in water electrolysis. This work reports a scalable, oil-based method based on thermal decomposition or organometallic complexes to yield highly uniform Ni-Fe-based nanocatalysts with well-defined morphology (i.e., Ni-Fe core-shell, Ni/Fe alloy, and Fe-Ni core shell).
