[Display omitted] The overall hydrazine splitting (OHzS) is a promising strategy to achieve the efficient hydrogen production in seawater through replacing the slow kinetic oxygen evolution reaction (OER) and toxic chlorine evolution reaction (ClOR) by hydrazine oxidation (HzOR). We report an efficient bifunctional electrocatalyst of Ni/Ni 3 S 4 /1T-MoS 2 on carbon cloth (Ni/Ni 3 S 4 /1T-MoS 2 /CC), which was formed from large layer spacing MoS 2 and Ni 3 S 4 with metal-Ni, and was applied as for both hydrogen evolution reaction (HER) and HzOR. The MoS 2 had expanded interlayer spacing and showed 1T phase, with significantly improved conductivity and hydrophilicity, which promotes transfer process of reactants. Furthermore, the introduction of Ni/Ni 3 S 4 on the 1T-MoS 2 base surface leaded to superhydrophilic and superaerophobic properties, which makes it more conducive to the adsorption of H. The improvement of electrical conductivity induced the excellent HER and HzOR electrocatalytic properties of Ni/Ni 3 S 4 /1T-MoS 2 /CC, which showed an ultralow overpotential of 24 mV and working potential of 0 mV at a current density of 10 mA cm−2, respectively. Inspiringly, Ni/Ni 3 S 4 /1T-MoS 2 /CC also showed excellent performance in hydrazine-assisted alkaline seawater electrolysis, as well as solar panel powered electrolysis of seawater OHzS, therefore, exhibiting great potential for practical applications.
