【摘要】 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。

【Abstract】 Calix[4]arene-acetate/TiO2(CA/TiO2) hybrid materials with different TiO2 content were prepared by sol-gel method.According to FT-IR showed that there was the chemical bond between the TiO2 phase and the polymer matrix in the hybrids.CA/TiO2 hybrid materials were investigated through the methods of XRD.For testing the photocatalysis performance of the products,we took the methyl orange solution as the water sample,completed a series of comparable experiments of photocatalysis degradation.The results showed that at w(TiO2)=50%,The hybrid materials acquired more excellent biphase compatibiuty and exhibited higher photocatalytic activity.
