Fund Project: This work was supported by the National Natural Science Foundation of China (21876069, 21707054), the Six Talent Peaks Project in Jiangsu (XCL-018), and the China Postdoctoral Science Foundation (2016M601744).

Herein, we report a unique approach towards the preparation of C-modified and N-doped TiO₂ hollow spheres (C/N-TiO₂). TEM, SEM, and XPS analyses were used to confirm that the carbon and nitrogen co-decorated TiO₂ photocatalyst was formed. Carbon-decoration improves the visible-light absorption and speeds up the separation of the photo-generated electron-hole pairs. C/N-TiO₂ not only narrows the band gap of TiO₂, but also exhibits excellent photocatalytic activity for the degradation of tetracycline and tetracycline hydrochloride. In addition, the C/N-TiO₂ photocatalyst shows excellent recyclability for water decontamination, making it a promising candidate to purify aquatic contaminants.
