摘要：

We developed a facile hydrothermal method to fabricate the carbon quantum dots (CQDs)/MoS₂ composite as hydrogen evolution reduction (HER) catalyst. After irradiation with visible light for 30 min, the CQDs/MoS₂ composite (as CQDs/MoS₂-L30) performed improved HER activity, featured by a small overpotential of ~0.125 V at 10 mA cm^-2, a high current density, a small Tafel slope of 45 mV/decade and a long term stability in 0.5 M H₂SO₄. This kind of activity improvement towards HER may be due to the high charge transfer efficiency, the decrease of S⁴⁺ and the increase of S2^2- and S^2- after the light treatment.
