摘要
利用高压静电纺丝制备了具有良好耐光降解性能的羧基聚砜电纺纤维毡,利用其为载体用水热反应法制备了ZnS/TiO2聚砜复合光催化材料,得到了分布均匀的ZnS/TiO2聚砜纤维复合材料。通过X射线衍射、光电子能谱、紫外-可见漫反射光谱、热失重、耐紫外光降解实验对复合材料进行了表征。光催化分解水制氢实验表明:ZnS/TiO2含羧基聚砜纤维复合材料的催化效率高于同等条件下粉体ZnS/TiO2,并且具有很好的重复稳定性。
In A carboxylic polysulfone fiber mat with good anti-degradation under irradiation was prepared by electrospinning. It was used as carrier for ZnS/TiO2 photocatalyst which was prepared by hydrothermal method. The ZnS/ TiOe carboxylic polysulfone fibers was characterized by X-ray diffraction, electron spectrum, ultraviolet visible diffuse reflectance spectrum, thermogravimetric analysis and the experiment of light degradation resistance. The experiment of pho- tocatalytic hydrogen production from water was also studied, the result showed that the photocatalytic ability of ZnS/TiO2 carboxylic polysulfone fiber composites was better than that of ZnS/TiO2 particle, which also boasted good recycle ability and great stability.
