Sunlight promoted self-fenton photodegradation and pathway of doxycycline: Interactive effects of nanomaterial on bean plant and its genotoxicity against Allium cepa

Photocatalytic induction of electron/hole recombination, surface property and light response ability effectively
enhance the photocatalytic activity of nanomaterial. In this work, the effective charge carrier separating
Sn/Mn–ZnFe2O4–CdFe2O4–Ag3PO4 Quantum dots (M/SZFO–CFO–AP QDs) was fabricated for photocatalytic
degradation of doxycycline (doxy) antibiotic. The result showed enhanced photocatalytic activity of doxy and
the degradation efficiency of doxy was about 98.8% in short span of time. The calculated WH plot and urbach energy
of prepared photocatalyst exhibited evidence for the prevalence of point defects and its contribution to efficient
charge separation and transferability. The total organic carbon (TOC) removal was found to be 98.9%,
which depicts the complete mineralization of doxy. The synergetic charge transfer of n-p-n heterojunction enables
the effective removal of doxy under visible light irradiation. Further, the genotoxicity study was determined
by interacting the SZFO–CFO–AP QDs with Allium Cepa. The results depict that SZFO–CFO–AP QDs show
lower toxicity level and there were no trace of defective mitotic phases and micro nuclei. Further, the progression
and development of bean plant was determined after treating with prepared nanomaterials and the result showed
the enhanced growth in SZFO–CFO–AP QDs treated bean plant compared to the counterparts. Therefore, the prepared
SZFO–CFO–AP QDs was can be used as an environmental friendly photocatalyst for effective treatment of
antibiotic present in the water bodies.
