Magnetically recyclable spherical CuO@FeO S-scheme heterojunction for efficient tetracycline removal visible light-activated peroxydisulfate.

The overuse of antibiotics in treating bacterial infections is a significant threat to the environment and human health. The utilization of visible-light-assisted peroxydisulfate (PDS) activation for eliminating organic pollutants is a promising approach. This study uses a straightforward hydrothermal method to prepare magnetically recyclable spherical CuO@FeO.
