Conventional noble metal catalysts such as Pt and Au face limitations in large-scale hydrogen production due to their scarcity and high cost. Molybdenum disulfide (MoS2)-based alternatives have attracted attention as non-precious HER catalysts, but their catalytic performance is hindered by poor conductivity and insufficient exposure of active edge sItes. In this study, we report a hybrid catalyst composed of amorphous molybdenum sulfide (MoSx) conformally coated on a vertically aligned N-doped carbon nanotube (NCNT) forest. The N-doped graphitic surface promotes electrostatic adsorption of precursors. The resultung ~2nm-thick amorphous MoSx layer exposes abundant unsaturated fulfur sites for proton adsoprtion, while the conductive NCNTs provide efficient charge transport pathways to the electrode. This synergistic nanostructure achieves an outstanding performance for hydrogen evolution reaction and excellent durability, demonstrating its potential for hydrogen energy industry.
