Enhances oxygen evolution reaction efficiency in nickel phosphide composites, indicating a path to better hydrogen production.

The aim is to improve the electrochemical performance of nickel phosphide for efficient oxygen evolution reactions.
Incorporation of iron, manganese, or nickel species into nickel phosphide nanoparticles.
Anchoring synthesized nanoparticles onto a cellulose-derived carbon support.
Characterization using electrochemical impedance spectroscopy to evaluate charge transfer resistance.
The cel_Ni2P_Fe10 composite achieved an overpotential of 172.5 mV at 10 mA·cm–2.
Tafel slope measured at 55.6 mV·dec–1 indicates efficient charge transfer.
Significantly reduced charge transfer resistance compared to benchmark RuO2 catalyst.
