英文摘要	NiS was loaded on ZnS₁_{_}_x_{_}_0.5_yO_x(OH)_y-ZnO photocatalyst by two methods (depositing NiS on the photocatalyst via impregnation with a NiS sol and via a precipitation reaction). The activity of the NiS-modified photocatalyst for hydrogen evolution from pure water and seawater was investigated using mixed electron donors (sulfide and sulfite). The activity (in pure water-electron donor solution) is dependant of the modification method and loading content of NiS. When Na₂S·9H₂O and Na₂SO₃ are added into seawater, a mixture precipitate (Mg(OH)₂ and CaSO₃) produces. The precipitate is detrimental to the photocatalytic hydrogen evolution over the unmodified ZnS₁_{_}_x_{_}_0.5_yO_x(OH)_y-ZnO. However, for the NiSmodified photocatalyst, the detrimental effect decreases notably. Interestingly, the activity of the modified photocatalyst in seawater-electron donor solution (with the precipitate) is higher than that in the pure water-electron-donor solution (without the precipitate). The possible mechanism was discussed.
