Abstract

Developing economic, efficient, and stable electrocatalysts for accelerating the hydrogen evolution reaction (HER) remains challenging. Here, MoS₂/rGO electrocatalysts were prepared by a simple one-pot hydrothermal process for efficient HER in water splitting. Meanwhile, the MoO₃ and 1T/2H-MoS₂ species on the surface of rGO have the capability to furnish more electrocatalytic active sites. The obtained MoS₂/rGO catalyst exhibits excellent HER activity with the low overpotential of 429 mV at 10 mA cm⁻² current density, and the Tafel slope of 134 mV dec⁻¹. This study provides a new idea for the development of novel electrocatalysts for application in electrochemical energy devices.
