Abstract
The use of tetracycline (TC-HCl) antibiotics is harmful to ecosystems worldwide. Herein, NiFe2O4/Ag2WO4nanocomposite (NC) was synthesized via the hydrothermal method for the degradation of tetracycline. The photodegradation efficiency of TC-HCl reached 92.3% after being exposed to visible light for 90 min. Additionally, the stability of the NiFe2O4/Ag2WO4nanocomposite is maintained during the photodegradation of tetracycline, as verified by the recyclability test. Degradation efficiency up to 83% was still present after six cycles. The presence of DMPO-∙O2- and DMPO-•OH is confirmed by the ESR study, when the visible exposure period expanded to 15 min. High photocatalytic performance, strong recyclability, and stability make NiFe2O4/Ag2WO4a potential antibiotic photodegradation candidate.
