MoS₂ is a promising catalyst for hydrogen evolution reaction, whereas the inherent defects of limited active sites for H₂ evolution and poor conductivity impede its practical application. Herein, low-cost and available activated carbon (denoted as C) was introduced and MoS₂/C composite was prepared via a facile one-pot liquid-phased reaction. The MoS₂/C exhibits an excellent photocatalytic hydrogen evolution activity (872.3 μmol/h) sensitized by Erythrosin B under LED light irradiation, which is about 1.8 times that of pure MoS₂. Moreover, hydrogen evolution mechanism and reasons for the enhanced performance of MoS₂/C were proposed based on the results of photoluminescence spectra and photoelectrochemical tests.

MoS ₂是用于氢释放反应的有前途的催化剂，而有限的H ₂释放活性位和固有的导电性的固有缺陷阻碍了其实际应用。在此，引入了低成本且可用的活性炭（表示为C），并通过简便的一锅液相反应制备了MoS ₂ / C复合材料。MoS ₂ / C表现出优异的光催化脱氢活性（872.3μmol/ h），在LED光照射下，赤藓红B对其增敏，约为纯MoS _2的1.8倍。此外，析氢机理和MoS ₂性能增强的原因基于光致发光光谱和光电化学测试的结果提出了C。
