Abstract Photocatalytic degradation is one of the most promising methods for addressing environmental issues without introducing pollution sources. Nonetheless, majority works are devoted to explore high‐efficiency semiconductor photocatalysts, but potential risks in their application usually neglected. In this work, an environmentally friendly vesicle‐structured photocatalyst rationally designed by employing magnetic layered double oxide‐hollow spheres@antimony tin oxide as a core, phospholipid membrane, and carbon nanotubes (CNTs) channels, yielding multi‐structural material with robust organic pollutants photocatalytic mineralization ability. Materials characterization, computational modeling, cytotoxicity tests suggest that under visible light irradiation, photogenerated charges can be rapidly generated transfer core composite, H 2 O effectively activated generate hydroxyl radical rapid degradation. The construction membranes embedded CNTs not only maintains photodegradation performance material, also restrains its risk. Such synthetic approach advances development bionic materials.

Photocatalytic Degradation of Tetracycline by La-Fe Co-Doped SrTiO3/TiO2 Composites: Performance and Mechanism Study

Human health, as well the ecosystem’s natural equilibrium, may be jeopardized by discharge of tetracycline into aquatic environment. In order to effectively photocatalyzed degradation in aqueous solution under visible light, this study used a two-step hydrothermal approach produce composites SrTiO3/TiO2 doped with two metal elements, lanthanum (La) and iron (Fe). The crystal structure, morphology, electronic particle size, specific surface area photocatalytic properties catalysts were assessed using variety methods, such fluorescence spectroscopy, UV-Vis diffuse reflectance, X-ray diffraction, scanning electron microscopy, BET size analysis. After 120 min exposure co-doped catalyst showed rate 99.1%, which was nine times greater than that at dosing 1.6 g/L concentration 20 mg/L. synthesized photocatalyst exhibited good tolerance changes pH, efficiency remaining stable within pH range 4–10. La-Sr (Ti-Fe) O3/TiO2 also demonstrated excellent photostability after recycling. mechanism is primarily attributed active oxidation photogenerated holes •O2−. Furthermore, pathways analyzed via HPLC-MS identify intermediates.
