Abstract

Hydrogen evolution reaction performance of MoS₂ can be enhanced through electric-field-facilitated electron transport. The best catalytic performance of a MoS₂ nanosheet can achieve an overpotential of 38 mV (100 mA cm^-2 ) at gate voltage of 5 V, the strategy of utilizing the electric field can be used in other semiconductor materials to improve their electrochemical catalysis for future relevant research.

Keywords: MoS2 nanosheets; electrochemical catalysis; field effect; hydrogen evolution reaction.
