Abstract

The hydrogen evolution reaction (HER) on carbon supported MoS2nanoparticles is investigated and compared to findings with previously published work on Au(111) supported MoS2. An investigation into MoS2oxidation is presented and used to quantify the surface concentration of MoS2. Other metal sulfides with morphologies similar to MoS2 such as WS2, cobalt-promoted WS2, and cobalt-promoted MoS2 were also investigated in the search for improved HER activity. Experimental findings are compared to density functional theory (DFT) calculated values for the hydrogen binding energies (ΔGH) on each system.
