An efficient electrocatalyst for hydrogen evolution has been developed based on liquid exfoliation of bulk MoS2 via a direct dispersion and ultrasonication method. Transmission electron microscopy and atomicforce microscopy measurements show that the exfoliated MoS2 consists of two-dimensional nanosheets. The exfoliated MoS2 nanosheets modified glass carbon electrode (E-MoS2/GCE) with various loadings is fabricated via a drop-casting method. The electrocatalytic activity of E-MoS2/GCE toward hydrogenevolution reaction is examined using linear sweep voltammetry. It is shown that the E-MoS2/GCE withan electrode loading of 48 ug cm-2 exhibits a high catalytic activity for hydrogen evolution with a lowoverpotential (-0.12 V) and a high current density (1.26 mA cm-2, at n = 150 mV).
