The development of efficient electrocatalysts for oxygen evolution reaction (OER) is essential for the practical application of water splitting. Herein, iron phosphate (FePi) electrode is synthesized using a successive ionic layer deposition and reaction (SILAR) method on a nickel foam substrate at room temperature and is used as electrocatalyst for water splitting. The prepared FePi electrodes show excellent electrocatalytic activity and stability for the oxygen evolution reaction (OER). The FePi electrode exhibits low overpotential of 235 mV at 10 mA cm-2 current density. The better OER activity of both films originated from high active sites, enhanced surface, and charge transport capability. |
