Enhancing Hydrogen Evolution Reaction via Synergistic Interaction between the [Mo₃S₁₃]^2- Cluster Co-Catalyst and WSe₂ Photocathode.

ABSTRACT: A thiomolybdate [Mo₃S₁₃]^2- nanocluster is a promising catalyst for hydrogen evolution reaction (HER) due to the high number of active edge sites. In this work, thiomolybdate cluster films are prepared by spin-coating of a (NH₄)₂Mo₃S₁₃ solution both on FTO glass substrates as hydrogen evolving electrodes and on highly 00.1-textured WSe₂ for photoelectrochemical water splitting. As an electrocatalyst, [Mo₃S₁₃]^2- clusters demonstrate a low overpotential of 220 mV at 10 mA cm^-2 in 0.5 M H₂SO₄ electrolyte (pH 0.3) and remain structurally stable during the electrochemical cycling as revealed by in situ Raman spectroscopy. Moreover, as a co-cata
