Abstract

Copper oxide nanoflowers (CuO-NFs) have been synthesized through a novel green route using Tulsi leaves-extracted eugenol (4-allyl-2-methoxyphenol) as reducing agent. Characterizations results reveal the growth of crystalline single-phase CuO-NFs with monoclinic structure. The prepared CuO-NFs can effectively degrade methylene blue with 90% efficiency. They also show strong barrier against E. coli (27 ± 2 mm) at the concentration of 100 µg mL−1, while at the concentration of 25 µg mL−1 weak barrier has been found against all examined bacterial organisms. The results provide important evidence that CuO-NFs have sustainable performance in methylene blue degradation as well as bacterial organisms.


Highlights:


1 Eugenol (4-allyl-2-methoxyphenol) extracted from O. sanctum leaves is used as a natural reducing agent for the synthesis of CuO nanoflowers (NFs).
2 CuO-NFs can degrade methylene blue with an efficiency of 90%.
3 CuO-NFs offer a new vision to deactivate multi-drug microorganisms.
