以Ti(OBu)4和杯[4]芳烃乙酸为前驱体,采用溶胶-凝胶法制备了不同TiO2含量的杯[4]芳烃乙酸/TiO2(CA/TiO2)材料。通过FT-IR测试表明,材料中有机无机两相间存在着化学键,并通过XRD对材料的结构进行表征。为了测试材料的光催化性能,以甲基橙溶液为模拟水样,进行了光催化降解的对比实验。结果表明:当TiO2的含量为50%(wt,下同)时,材料有机无机两相相容性和光催化性能最优。
Calix [4] arene / TiO2 (CA / TiO2) materials with different TiO2 contents were prepared by sol-gel method using Ti (OBu) 4 and calix [4] areneacetic acid as precursors. The results of FT-IR showed that there were chemical bonds between organic and inorganic phases in the material and the structure of the material was characterized by XRD. In order to test the photocatalytic properties of the material, methyl orange solution was used as a simulated water sample to carry out comparative experiments on photocatalytic degradation. The results show that when the content of TiO2 is 50% (wt, the same below), the compatibility of organic and inorganic phases and photocatalytic activity are the best.
