Abstract
HighlightsEugenol (4-allyl-2-methoxyphenol) extracted from O. sanctum leaves is used as a natural reducing agent for the synthesis of CuO nanoflowers (NFs).CuO-NFs can degrade methylene blue with an efficiency of 90%.CuO-NFs offer a new vision to deactivate multi-drug microorganisms.
Highlights
The micro-/nanostructure studies demand a better understanding of crystal facet engineering with tailored architecture that can be attained by the new design and facile synthesis methods [1,2,3]
The aim of the present work is to synthesize cupric oxide (CuO) nanostructures using eugenol extracted from O. sanctum leaves (the detailed eugenol isolation procedures are shown in Electronic Supporting Information (ESI)), and the obtained product was evaluated for the photocatalytic activity against the organic dye for water rectification and bacteria killing
On the basis of the results and discussion of the present study, we can summarize that the flower-shaped CuO-NSs can successfully be synthesized via green route using Ocimum sanctum (Tulsi) leaves-extracted Eugenol (4-allyl2-methoxyphenol) as a capping agent as well as the stabilizing agent
Summary
The micro-/nanostructure studies demand a better understanding of crystal facet engineering with tailored architecture that can be attained by the new design and facile synthesis methods [1,2,3]. CuO nanostructures with large surface areas and potential size-effects possess superior physical and chemical properties that remarkably differ from those of their microor bulk counterparts [5]. It has excellent architectures with different shapes and dimensions, such as zero-dimensional (0D) nanoparticles, one-dimensional (1D) nanotubes, 1D nanowires/rods, two-dimensional (2D) nanoplates, 2D nanolayers as well as several complex three-dimensional (3D) nanoflowers, urchin-like and spherical-like nanostructures [6, 7]. Several important innovations have been directed toward the production of CuO, out of which many of them involve complexity of chemical reactions and problems associated with the reproducibility [1]
