V-doped MoS2-NixSy/NF hollow nanospheres by an in situ one-pot method showed excellent HER performance in 1 M KOH solution.
Ru nanoparticles/oxygen-deficient TiO2@carbon nanocomposites are efficiently fabricated via one-pot pyrolysis. TiO2-VO and carbon narrow the band gap, optimize ΔGH2O and ΔGH* and synergistically boost the activity of Ru for the alkaline HER.
