Abstract

Herein, a magnetic nanocomposite is synthesized using ZIF-8, g-C3N4, and MnFe2O4 (g-C3N4/ZIF-8/MnFe2O4) as photocatalyst for the tetracycline hydrochloride photodegradation. Characterization of the nanocomposite was verified with various methods containing XRD, FT-IR, FE-SEM, TEM, EDS, elemental mapping, DRS, PL, and EIS. Then, its application as photocatalysts for the tetracycline hydrochloride degradation is studied under visible light illumination. Using this photocatalyst, after 60 min, the conversion of tetracycline hydrochloride, is measured to be 98.8%. Also, average apparent reaction rate constant of photodegradation of tetracycline hydrochloride by g-C3N4/ZIF-8/MnFe2O4 nanocomposite was 9.7, 12.1, 15.6, 3.1, 3.7, and 4.8 times those of g-C3N4, ZIF-8, MnFe2O4, g-C3N4/ZIF-8, g-C3N4/MnFe2O4, and ZIF-8/MnFe2O4, respectively. In the radical scavenger, and ESR experiments, ˙OH, and h+ were exhibited to be major species in the photocatalytic degradation process. Furthermore, we proposed a mechanism for the degradation of tetracycline hydrochloride by g-C3N4/ZIF-8/MnFe2O4 nanocomposite. [ABSTRACT FROM AUTHOR]
