Residue organic matter such as antibiotics and dyes are left in wastewater that are difficult to remove. Herein, we reported a bismuth oxyiodide (Bi5O7I)/zeolite imidazolate framework-8 (ZIF-8) catalyst with an S-scheme heterojunction for the degradation of tetracycline (TC) using an in-situ growth strategy. The degradation process of TC is divided into two parts: adsorption and photocatalysis. Under dark reaction conditions, the Bi5O7I/ZIF-8 composites have an eminent adsorption effect on TC. When exposed to visible light, the resulting Bi5O7I/ZIF-8 composites revealed an outstanding photocatalytic activity and high stability toward TC degradation. Experiments utilizing active species trapping showed that O2is essential to the photocatalytic process and the efficacy of the process is further improved by the addition of h+and •OH. Likewise, these catalysts catalyzed the degradation of 84.6% of TC, and the Bi5O7I/ZIF-8 also exhibited high degradation stability after 4-cycle trial. This work optimizes the degradation performance of antibiotic residues by presenting a practical and doable approach for creating green semiconductor heterojunctions. |
