Electrocatalytic hydrogen evolution using the MS2@MoS2/rGO (M = Fe or Ni) hybrid catalyst

Chem Commun (Camb). 2016 Sep 27;52(79):11795-11798. doi: 10.1039/c6cc06180j.

Abstract

We established a three-tiered cake-like hybrid (MS2@MoS2/rGO, M = Fe or Ni) with the MS2 nanoparticles distributed over the platform of MoS2 and graphene (MoS2/rGO), which exhibits superior HER electrocatalytic activity as well as excellent electrochemical durability. The enhanced electrocatalytic activity benefits from the unique synergistic effects of graphene sheets enhancing the conductivity of the hybrid, MS2 (M = Fe or Ni) nanoparticles and MoS2 nanosheets providing abundant electrocatalytically active sites. Meanwhile, the mechanical stability is promoted by the meticulously-built cake-like structure.
