Background:

• Developing efficient electrocatalysts for oxygen evolution reaction (OER) is crucial for water splitting.
• Challenges include limited active sites and catalyst degradation during reactions.

Purpose of the Study:

• To prepare a novel OER electrocatalyst with high efficiency and stability using a simple method.
• To investigate the performance of Ru-doped Fe on nickel foam for water splitting.

Main Methods:

• Electrochemical characterization of the catalyst's OER performance.
• Assembly of an electrolytic cell for overall water splitting.

Main Results:

• Ru-0.01-Fe/NF-2.5 showed low OER overpotentials (134 mV at 10 mA cm⁻²).
• Overall water splitting required only 1.46 V for 10 mA cm⁻².
• The catalyst maintained stability for 48 hours at 100 mA cm⁻².

Conclusions:

• The developed Ru-doped Fe catalyst offers high efficiency and stability for water splitting.
• The facile synthesis method and excellent performance promote applications in industrial water electrolysis.
