以钛酸四丁酯(TBOT)为钛源,硅酸四乙酯(TEOS)为硅源,以非离子表面活性剂聚环氧乙烷-聚环氧丙烷-聚环氧乙烷三嵌段共聚物(P123)做模板剂,绿色无毒的表面活性剂司盘80(Span80)为扩孔剂,通过调节扩孔剂Span80与表面活性剂P123的配比以及TBOT与TEOS的配比利用水热法一步合成一系列Ti/Si复合材料。经过傅里叶变换红外光谱、扫描电子显微镜、BET比表面积测试、X射线衍射等手段对合成的Ti/Si复合材料进行表征,确定最佳比例的Ti/Si复合材料的制备方法。实验结果表明,在Span80质量为0.4 g,SiO2和TiO2摩尔比为8∶2时,所制得的Ti/Si复合材料Ti/Si-2具有最大比表面积,为470.76 m2/g,孔隙分布均匀。室温下,紫外光光照条件下2 h内对水中亚甲基蓝染料的降解效率可以达到99.3%,性能比商品化P25型纳米TiO2光催化剂更优良。

A series of Ti/Si composite photocatalysts were synthesized by one step hydrothermal method,with tetrabutyl titanate (TBOT) as the titanium source,tetraethyl orthosilicate (TEOS) as the silicon source, nonionic surfactant polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer (P123) as a template and green non-toxic surfactant Span80 as a pore-enlarging agent. The ratios of Span80/P123 and TBOT/TEOS were also adjusted. The synthesized Ti/Si composites were characterized by Fourier transform infrared spectroscopy,scanning electron microscopy,BET specific surface area and X-ray diffraction,respectively. The results show that the prepared titanium-silicon composite (Ti/Si-2) has the maximum specific surface area of 470.76 m2/g and uniform pore distribution when the mass of Span80 is 0.4 g and the mole ratio of SiO2 to TiO2 is 8∶2. The degradation efficiency of methylene blue dye with Ti/Si-2 as catalyst in water can reach 99.3% within 2 h under ultraviolet light,indicating the better performance compared with commercial P25 nano-TiO2 photocatalyst.
