| 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403.1μmol.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. |
