Abstract

In this study, we investigate the catalytic performance of molybdenum sulfide (MoS₂) modified with either nickel (Ni) or platinum (Pt) nanoparticles as catalysts for the hydrogen evolution reaction (HER). The MoS₂ was prepared on the TiO₂ nanotube substrates via a facile hydrothermal method, followed by the deposition by magnetron sputtering of Ni or Pt nanoparticles on the MoS₂ surface. Structural and morphological characterization confirmed the successful incorporation of Ni or Pt nanoparticles onto the MoS₂ support. Electrochemical measurements revealed that Ni- and Pt-modified MoS₂ catalysts exhibited enhanced HER activity compared to pristine MoS₂. Obtained catalysts demonstrated a low onset potential, reduced overpotential, and increased current density, indicating efficient electrocatalytic performance. Furthermore, the Ni or Pt-modified MoS₂ catalyst exhibited remarkable stability during prolonged HER operation. The improved catalytic activity can be attributed to the synergistic effect between metal nanoparticles and MoS₂, facilitating charge transfer kinetics and promoting hydrogen adsorption and desorption. Incorporating Ni and Pt nanoparticles also provided additional active sites on the MoS₂ surface, enhancing the catalytic activity.
