Abstract
Ru nanoparticles/oxygen-deficient TiO<sub>2</sub>@carbon nanocomposites are efficiently fabricated <italic>via</italic> one-pot pyrolysis. TiO<sub>2</sub>-V<sub>O</sub> and carbon narrow the band gap, optimize Δ<italic>G</italic><sub>H2O</sub> and Δ<italic>G</italic><sub>H*</sub> and synergistically boost the activity of Ru for the alkaline HER.
