Abstract

Facile solvothermal route was adopted for the synthesis of Co2xMo1-xS2 with x = 0, 0.05 and 0.1. Higher HER activity was exhibited by x = 0.1 in Co doped MoS2, with a current density -140 mAcm -2 at an overpotential of -100 mV. At lower overpotential both the compositions exhibited almost same activity, whereas with the increase in the overpotential and under continuous electrochemical operation, the active sites of composition with x = 0.1 was triggered and it was reflected in its HER activity.
