Recently, transition-metal dichalcogenides such as MoS₂ have been considered for application in hydrogen evolution catalysis. However, its use in the form of a single MoS₂ material is limited owing to its low charge-transfer rate. In this study, a MoS₂–Pd–Pt catalyst was fabricated on carbon paper using a simple two-step synthesis method. MoS₂ and MoS₂–Pd were synthesized via a simple hydrothermal method, and a small amount of Pt was electrodeposited on the prepared sample using a three-electrode system. The nanostructure of MoS₂–Pd has more defects than the structure of MoS₂, and the exposure of active sites is high, which is advantageous for the Pt deposition process. In the Pt electrodeposition process, MoS₂–Pd exhibited a higher deposition efficiency and stability than MoS₂ in an acidic medium. Although an exceedingly small amount of Pt was deposited, the hydrogen evolution reaction (HER) properties of MoS₂–Pd–Pt significantly improved compared to those of MoS₂–Pd. Moreover, MoS₂–Pd–Pt exhibited an excellent catalytic activity with a lower overpotential (−64 mV at 10 mA/cm²) compared to those of MoS₂ (−253 mV) and MoS₂–Pd (−204 mV), thereby proving it to be a promising electrocatalyst for the HER as an alternative to Pt.
