| 摘 要： | 采用溶胶-凝胶法与原位合成相结合的方法,合成了2,9,16,23-四磺基酞菁锌(ZnfsPc)/TiO2复合材料,用FTIR,UV-Vis,XRD,Zeta电位、荧光光谱等对复合材料进行了表征,同时对材料进行了可见光光催化反应实验.实验结果表明采用该原位自组装的方法,不仅在TiO2颗粒表面原位生成酞菁,还在TiO2表面形成化学键(-SO2-O-Ti-).有效地增强了ZnTsPc的敏化能力,使光生载流子形成有效的分离,从而大幅度地提高了复合材料的可见光光催化能力.

| Abstract: | Tetrasulfophthalocyaninatozinc/titanium dioxide (ZnTsPc/TiO2) was synthesized by a novel in-situ and self-assembly process. The prepared products, including pure TiO2 and ZnTsPc, were characterized by XRD, UV-Vis, FTIR, Zeta potential and fluorescence spectroscopic techniques. The results indicated that ZnTsPc was indeed synthesized during the in-situ method and sol-gel process. A chemical bond (--SO2--O--Ti--) was also formed between the sensitizer (ZnTsPc) and the surface of titanium dioxide particles. The photocatalyst of ZnTsPc/TiO2 reveals greatly enhanced activity for the degradation of organic pollutant, Rhodamine B, under visible-light irradiation as compared with pure TiO2 and P25. The sensitization mechanism is that photo-generated charge carriers are separated by the chemical bond between ZnTsPc and TiO2. |
