The electrocatalytic splitting of water via hydrogen evolution reaction (HER) is one of the most efficient technologies for hydrogen production, while the massive consumption of precious Pt‐based catalysts hinders its commercialization, bringing an urgent task to explore low‐cost and earth‐abundant alternatives. Herein, a cost‐efficient system composed of metal Pt/molybdenum disulphide (MoS 2 ) nanosheets hybrids for the HER by auxiliary of solar light is reported. The uniformly Pt nanoparticle decorated MoS 2 sheets can be easily obtained under hydrothermal condition using oleylamine as capping agent and N , N ‐dimethylmethanamide (DMF) as intercalation molecule for MoS 2 exfoliation. The Pt/MoS 2 hybrid shows a significantly enhanced HER activity compared with bare MoS 2 due to enhancing conductivity and reducing overpotential by electron transport between Pt and MoS 2 . As a result, a Tafel slope of 38 mV per decade is obtained, suggesting a highly efficient Volmer–Heyrovsky reaction of hydrogen evolution.
