Structural Properties of Gas Phase Molybdenum Sulfide Clusters [Mo₃S₁₃]^2-, [HMo₃S₁₃]^-, and [H₃Mo₃S₁₃]⁺ as Model Systems of a Promising Hydrogen Evolution Catalyst.

ABSTRACT: Amorphous molybdenum sulfide (MoS _x ) is a potent catalyst for the hydrogen evolution reaction (HER). Since mechanistic investigations on amorphous solids are particularly difficult, we use a bottom-up approach and study the [Mo₃S₁₃]^2- nanocluster and its protonated forms. The mass selected pure [Mo₃S₁₃]^2- as well as singly and triply protonated [HMo₃S₁₃]^- and [H₃Mo₃S₁₃]⁺ ions, respectively, were investigated by a combination of collision induced dissociation (CID) experiments and quantum chemical calculations. A rich variety of H _x S _y elimination channels was observed, giving insight into the s
