摘要

Density functional theory (DFT) calculations show that H-2 evolution is attributed to active sulfur hydrides derived from MoS2 complexes via two- or three-electron reduction from the synthesized [(PY5Me2)MoS2](2+). Water acts as a bridge for H-2 evolution from the intermolecular H+/H- coupling between sulfur hydride complexes and hydrated protons.
