Abstract
NiMoS nanohybrid, consisting in nanosheets of MoS2 mainly covering nanoparticles of NiS, capped by an oleylamine/oleic acid organic coating, has been successfully synthesized, on few layer graphene (FLG) obtained by physical exfoliation of graphite, by thermolysis of suitable precursors in organic solvent in the presence of surfactants. The samples were characterized by Raman Spectroscopy, Electron Microscopy, and X-ray diffraction, and tested for HER activity using a typical three-electrode setup.
We obtained excellent HER activity, with a Tafel slope of 45 mV/dec compatible with electrochemical desorption as rate limiting step and high current density values.
