Biosynthesis of the ZnO/SnO2 nanoparticles and characterization of their photocatalytic potential for removal of organic water pollutants

Plants are rich sources of antioxidant compounds including phenols and flavonoids. These antioxidants crucial elements in diet protect the body against oxidative stress. In this study, activity phenolic flavonoids mistletoe (Viscum album), as a substituent for synthetic antioxidants, was quantitatively investigated. The plant alcoholic (ethanol) extract used biosynthesis ZnO/SnO2 composite nanoparticles that were employed photodegradation three organic pollutants (Congo red (CR), Biphenyl A (BPA), tetracycline (TC)) under solar light. tests performed considering effect pH, photocatalyst dosage, temperature, initial concentration pollutants. obtained data analyzed by Pseudo-first-order kinetic model. most optimum conditions found to be: 5 mg/l pollutant concentration, 0.5 g/l acidic pH. reusability test implied remain stable can perform well even after 4 cycles reuse. Conclusively, Viscum album offers promising properties allows optimally photodegrade wastewater
