摘要: 先用各向异性的Au纳米星(AuNS)与TiO2复合构筑金属-半导体异质核壳结构,再将硫杂杯[4]芳烃(STC[4]A)功能化于TiO2/AuNS表面制得Au纳米星/TiO2/杯芳烃(AuNS/TiO2/ STC[4]A)复合光催化材料,并通过紫外可见光谱(UV-Vis)、Fourier变换红外光谱(FT-IR)和扫描电子显微镜(SEM)等对材料进行表征, 考察AuNS/TiO2/STC[4]A对罗丹明B(RhB)的光催化降解活性.  实验结果表明,AuNS/TiO2/STC[4]A对RhB降解率可达99%,5次循环实验后,降解率仅降低1.8%.

Abstract: Firstly,  the  metal-semiconductor heterogeneous core-shell  structure was constructed by the combination of anisotropic gold nanostars (AuNS)  and TiO2. Secondly, the sulfonatothiacalix[4]arene (STC[4]A) was functionalized on the surface of TiO2/AuNS to prepare AuNS/TiO2/calixarenes (AuNS/TiO2/STC[4]A) composite photocatalytic materials.  The materials were characterized by ultraviolet-visible spectrum (UV-Vis)  Fourier transform infrared spectrum (FT-IR), scanning electron microscope (SEM), and the photocatalytic degradation activity of  AuNS/TiO2/STC[4]A for Rhodamin B (RhB) was investigated. The experimental results show that the degradation rate of Rhodamine B by  AuNS/TiO2/STC\[4\]A  can reach  99%, after five cycles, the degradation rate only decreases by 1.8%.
