A Se-doped MoS sub(2) nanosheet for improved hydrogen evolution reaction

Thanks to the increase in the number of active sites and enhanced conductivity, the Se-doped MoS sub(2) shows excellent catalytic activity with a lower overpotential of -140 mV and a smaller Tafel slope of 55 mV dec super(-1), exhibiting enhanced catalytic performance compared with that of pristine...

Zusammenfassung:Thanks to the increase in the number of active sites and enhanced conductivity, the Se-doped MoS sub(2) shows excellent catalytic activity with a lower overpotential of -140 mV and a smaller Tafel slope of 55 mV dec super(-1), exhibiting enhanced catalytic performance compared with that of pristine MoS sub(2). This work offers an attractive strategy to improve the HER activity of MoS sub(2)-based catalysts.
