Facile Spin-Coated MoS₂ Thin Films from a Single-Source Precursor for HER Activity.

ABSTRACT: Hydrogen evolution reaction (HER) is one of the most promising ways to replace the consumption of fossil fuels with a clean and green energy source. HER requires a suitable material as a catalyst to lower overpotential and minimize energy consumption. MoS₂ is an excellent candidate for the HER because of its suitable band structure. It is an economical and earth-abundant material compared to the standard electrode for HER, i.e., Pt. MoS₂ thin films can be engineered to produce active sites for HER. We prepared large area thin films of MoS₂ from a Mo single source precursor (MoCl₅) by means of spin coating, followed by post-annealing (sulfurization) with an additional sulfur source in an Ar/H₂ environment. The obtained films have been c
