Randomized trial demonstrates improved oxygen evolution reaction in alkaline water electrolysis, suggesting a promising alternative for green hydrogen production.
Key Points
The study aims to develop a highly active non-noble metal electrocatalyst for the oxygen evolution reaction during alkaline water electrolysis.
Synthesis of Sn-doped FeOx composite powder using a single-step hydrothermal method.
Evaluation of OER performance measured by overpotential and Tafel slope in 1 M KOH.
Durability testing at higher current density for assessing activity retention.
SnFeOx exhibited a low overpotential (η100) of 288 mV at 100 mA cm–2 with a Tafel slope of 35 mV dec–1.
Demonstrated >99% activity retention after 50 hours during durability tests at 100 mA cm–2.
Showed superior performance in full-water splitting compared to standard Pt/C and Ru/C configurations.
