Amorphous molybdenum sulfide

Amorphous molybdenum sulfide (MoSx) is a highly active noble-metal-free electrocatalysis for the hydrogen evolution reaction (HER). The MoSx was prepared by electrochemical deposition at room temperature. Low-cost precursors of Mo and S were adopted to synthesize thiomolybdates solution as the electrolyte.

Amorphous molybdenum sulfide (MoSx ) is an attractive Pt-free catalyst for the hydrogen evolution reaction (HER) in both neutral and acidic pH electrolytes. Among the available approaches for the preparation of MoSx , the electrochemical oxidation and reduction of a tetrathiomolybdate salt ([MoS4 ] 2-) represents the most convenient. Herein we describe new insights onto the electrochemical oxidation of [MoS4 ]2- to grow MoSx thin films by employing an advanced technique called electrochemical quartz crystal microbalance (EQCM).
