title = "Improved electrochemical activity from Ru doped WS2nanosheet catalyst",
abstract = "Two-dimensional layered materials (MoS2 and WS2) are well-known semiconductors and possess interesting physical properties. The nanostructures of these materials with active edge sites exhibit excellent electrocatalytic activity in acidic and alkaline conditions. Transition metal doping is one great research strategy that made the advancement of electrocatalytic behavior layered semiconductors. Here, the investigations on the electrochemical activity towards HER and supercapacitor studies of Ru doped WS2 nanosheets are presented. XRD analysis reveals that the Ru doped WS2 nanosheets exhibit a 2H-hexagonal crystal structure with evidence Ru was successfully incorporated in the WS2 crystal lattice. It is found that the HER overpotential of the catalyst is decreased with increasing Ru content and reaches the value 103 mV (at 10mA/cm2) for 12 at% of Ru from 186 mV of undoped WS2. Further, the electrochemical double layer capacitance of WS2 is increased with Ru content and the best catalyst of 12 at% of Ru possesses 33.04 mF/cm2 specific capacitance. Clearly, Ru doping has a beneficial effect on the electrocatalytic activity of WS2 nanosheets.",
