Abstract

In recent decades, the analysis of nanoparticles is of greater importance for their applications in various felds. This present
work also focuses the novel biological green material to synthesize the copper and cobalt oxide (Co3O4) nanoparticles. The
copper oxide (CuO) and Co3O4 nanoparticles (nps) have been synthesized by biological strategy utilizing (Araucaria heterophylla) AH gum extract. The characterization techniques, i.e. UV, GC–MS, FT-IR, XRD, SEM, HR-TEM provide concrete
information about the morphology, crystalline nature and structure of the synthesized nanoparticles. The high resolution
TEM and SAED images confrm the formation of spherical shaped (Co3O4) and oval shaped (CuO) isolated nanoparticles.
The catalytic adequacy of the developed catalyst, CuO and Co3O4 nanoparticles was analyzed for the degradation of dyes:
Methylene Blue, Congo Red, Acid Violet.The kinetic investigations for the reduction of synthetic dyes by the nanoparticles
were assessed and the reduction contemplates are very much ftted with the pseudo second order kinetic model with less
time. The antibacterial and antifungal activity of the prepared nanoparticles have been evaluated against Escherichia coli,
Staphylococcus aureus, Bacillus subtilis, Aspergillus niger and Candida albicans.
