Fabrication of MoS2/reduced graphene oxide hybrid as an earth-abundant hydrogen evolution electrocatalyst

MoS2/reduced graphene oxide (MoS2/rGO-NP) hybrid is fabricated through one-pot hydrothermal route with mediation of a water-soluble N-methylimidazole pillar[5]arene supramolecule. MoS2 sheets with more exposed active edge sites are well dispersed on the rGO surface. Electrochemical measurements demonstrate that MoS2/rGO-NP hybrid exhibits outstanding electrocatalytic performance for hydrogen evolution reaction with a low Tafel slope of 44.5 mV/dec and significantly enhanced kinetics. Thus, the MoS2/rGO-NP hybrid holds high potential as a promising earth-abundant electrocatalyst for the cost-effective production of hydrogen.
