Abstract

Amorphous MoS₂ porous thin films (denoted as MoS₂ PTFs) with high activity towards hydrogen evolution reaction (HER) were fabricated by in situ sulfuration of a Mo substrate. A small overpotential (∼120 mV) and a low Tafel slope (∼41 mV dec⁻¹) can be observed and their excellent performance was ascribed to the combination of the amorphous feature, porous structure and optimized thickness.
