Molybdenum Sulfide Supported on Crumpled Graphene Balls for Electrocatalytic Hydrogen Production

Abstract

MoSx is grown on crumpled graphene particles supported on carbon cloth substrates for the hydrogen evolution reaction. Modifying carbon cloth with crumpled graphene allows for higher loading levels of MoSx and thus significantly enhances its electrocatalytic activity. Measurements yield a current density of –220 mA cm−2 at an overpotential of 0.3 V (before iR correction) for the crumpled-graphene-modified carbon cloth.
