Synergistic effects boosting hydrogen evolution performance of transition metal oxides at ultralow Ru loading levels.

ABSTRACT: In this study, ultralow ruthenium nanoparticles on the nickel molybdate nanorods grown on nickel foam (Ru-NiMoO₄-NF) were synthesized. The Ru-NiMoO₄-NF exhibited outstanding hydrogen evolution reaction performances in alkaline with overpotential of 52 mV at the current density of 10 mA cm^-2. And, it maintains excellent stability for 20 h at the current density of 20 mA cm^-2. The mass activity of Ru-NiMoO₄-NF is 0.21 A mg_Ru ^-1, which is higher than that of Pt/C. Lots of exposed heterojunction interfaces and synergistic effects between Ru nanoparticles and NiMoO₄ nanorods were regarded as the reasons for excellent performance. This work provides an innovative route for developing low-cost catalysts based
