| description | The harmful effects of antibiotics on aquatic environments have become a growing concern of modern society. Developing high-performance photocatalysts capable of degrading antibiotics under solar light is, therefore, crucial. In this study, TiO<sub>2</sub>-cuttlebone composites are prepared via the sol–gel method, to produce carbonate radicals (•CO<sub>3</sub><sup>−</sup>) under solar light irradiation. The •CO<sub>3</sub><sup>−</sup> radicals exhibit high selectivity for the degradation of tetracycline hydrochloride (TC). Compared to TiO<sub>2</sub> alone, the TiO<sub>2</sub>-cuttlebone composite demonstrates excellent solar-driven photocatalytic activity for TC degradation in both freshwater and seawater. The reaction pathways of TC degradation in seawater are elucidated using HPLC-MS/MS analysis. Moreover, a TiO<sub>2</sub>-cuttlebone self-suspending photocatalyst device is fabricated using 3D printing technology and low-temperature deposition methods, with aluminum–plastic (AP) as a substrate. This innovative device is easily recyclable from photocatalytic solutions while maintaining high stability, making it highly desirable for practical applications. |
