ABSTRACT

The hydrogen economy and fuel cells represent the next great race for the industry. Hydrogen gas is a clean, highly abundant, and non-toxic renewable fuel that, when burned, releases only water vapor into the environment. In this study, we developed a new electrocatalyst consists of Co-MoS2/NiCoS/rGO through a simple hydrothermal method. This catalyst, shows a nano flower-like Co-MoS2/NiCoS structure on reduced graphene oxide and also exhibits ultrahigh HER (hydrogen evolution reaction) activity and excellent cycle stability. The optimal Co-MoS2/NiCoS/rGO hybrid shows excellent HER activity with a small overpotential and a low Tafel slope, along with good stability. Our work provides an effective way to produce other electrocatalysts based on interface structure and electronic conductivity engineering for HER in the future

Keywords: Hydrogen, Electrocatalyst, Hydrothermal, Over potential.
