Synergistic MoS2–Gold Nanohybrids for Sustainable Hydrogen Production Shrouq H. Aleithan, Shroq S. Laradhi, Kawther Al-Amer, Hany M. Abd El-Lateef Catalysts, 2025 Extensive research has been conducted on the catalytic properties of molybdenum disulfide (MoS2) materials in the context of the hydrogen evolution reaction (HER). This study focuses on exploring hybrid MoS2/Au structures as a catalyst for HER, utilizing linear sweep voltammetry as the experimental methodology. Firstly, 2D-MoS2 flakes were synthesized by the chemical vapor deposition (CVD) approach and directly added to gold nanoparticles during or after their preparation process. The prepared nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy with energy-dispersive X-ray analysis (SEM/EDX). The HER performance was tested for the two resulting samples to show that the preparation of gold nanoparticles with the coexistence of CVD-MoS2 flakes produces a superior electrocatalytic performance of the sample in a neutral medium. Notably, the onset potential was measured as −0.152 V (versus reversible hydrogen electrode (RHE)) with an exchange current density (j0) of 0.22 mA/cm2. Chronoamperometric data show that all composites retained initial current densities for 15 hours, confirming stable, efficient HER performance post-decay.
