Abstract

We demonstrate a heterostructure Ni₉S₈/MoS₂ hybrid with tight interface synthesized via an improved hydrothermal method. As compared to pure MoS₂, the increased surface area and the shorten charge transport pathway in the layered hybrid significantly promote the photocatalytic efficiency for hydrogen evolution reaction (HER). In particularly, the optimized Ni₉S₈/MoS₂ hybrid with 20 wt % Ni₉S₈ exhibits the highest photocatalytic activity with HER value of 406 μmolg^-1h^-1, which is enhanced by 70% compared to that of pure MoS₂ nanosheets (285.0 μmolg^-1h^-1). Moreover, the value is 4 times more than the commercial MoS₂ (92.0 μmolg^-1h^-1), indicating the high potential of the hybrid in the catalytic fields.
