| 摘要: 构建了曙红-碳纳米管-CuO/CoO光催化体系(Eosin Y-MWNTs-CuO/CoO)，并利用三乙醇胺作为牺牲剂考察了其可见光催化还原水制氢性能。结果表明，Eosin Y-MWNTs-CuO/CoO是一个高效的可见光催化剂，其光催化还原水析氢的速率可达403.1 μmol·g-1·h-1。同时，还研究了溶液pH值、CuO/CoO负载量等因素对光催化体系活性的影响，并对Eosin Y-MWNTs-CuO/CoO的光催化机制进行了初步探讨。 |

| Abstract: A photocatalytic system containing Eosin Y, multiwalled carbon nanotubes (MWNTs) and CuO/CoO (Eosin Y-MWNTs-CuO/CoO) was fabricated. Photocatalytic hydrogen evolution over the system was investigated using triethanolamine as a sacrificial reagent. The results display that Eosin Y-MWNTs-CuO/CoO is an efficient photocatalyst with the highest rate of 403.1 μmol·g-1·h-1 for H2 evolution under visible irradiation. Meanwhile, the photocatalytic hydrogen evolution was studied as function of reaction conditions, such as content of CuO/CoO, molar ratio of CuO to CoO, pH value of the solution, respectively. Furthermore, the photocatalytic mechanism is discussed. |
