Hydrothermally synthesized MoS2/ZnS heterostructure with efficient catalytic performance for hydrogen evolution

A novel hierarchical MoS2/ZnS heterostructure is synthesized hydrothermally and used as an electrode-active material for electrocatalytic hydrogen evolution reaction. The MoS2/ZnS heterostructure electrode shows a lower Tafel slope of ∼94.22 mV/dec with an overpotential of 271.53 mV, this highly efficient catalytic performance arises from the synergistic effect of the individual counter-parts.
