| 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%. |
