Ultrafine Fe1Pt3 nanoalloys on MoS2 nanosheets for robust hydrogen evolution reaction

In this study, Fe1Pt3 nanoparticles are dispersed on MoS2 nanosheets to integrate the fascinating features of noble metal with highly exposed nanosheets. The MoS2 nanosheets supply good support for the uniform dispersion and easily accessibility of Fe1Pt3 nanoalloys, and ultrafine Fe1Pt3 nanoparticles provide a large number of active sites and enhanced catalysis/charge kinetics. The Fe1Pt3-MoS2 catalyst exhibits good hydrogen evolution performances in acidic media with low overpotential of 59 mV at current density of 10 mA cm(-2) and robust catalysis kinetics (Tafel slope of 38 mV dec(-1)), making it high-efficiency HER catalyst with low Pt loading.
