Thanks to the increase in the number of active sites and enhanced conductivity, the Se-doped MoS2 shows excellent catalytic activity with a lower overpotential of -140 mV and a smaller Tafel slope of 55 mV dec(-1), exhibiting enhanced catalytic performance compared with that of pristine MoS2. This work offers an attractive strategy to improve the HER activity of MoS2-based catalysts.
