Ru-Doped Fe₂TiO₅ as a High-Performance Electrocatalyst for Urea-Assisted Water Splitting.

The urea oxidation reaction (UOR), with its low thermodynamic potential, offers a promising alternative to the oxygen evolution reaction (OER) for efficient hydrogen production. However, its sluggish kinetics still demand the development of an efficient electrocatalyst. In this study, the critical role of Ru doping in Fe₂TiO₅ is demonstrated to accelerate UOR kinetics.
