Ru (∼0.24 wt%) anchored on Mo@MoO_x nanowires (Ru−Mo@MoO_x) is fabricated as a self-supported cathode for efficient alkaline HER. The Ru−Mo@MoO_x nanowires exhibit a considerably low overpotential of only 16 mV at 10 mA cm⁻² and a Tafel slope of ∼30 mV dec⁻¹ in a 1 M KOH aqueous solution, which outperform those for commercial Pt/C and most reported Ru-based electrocatalysts.
