Abstract

In recent decades, the analysis of nanoparticles is of greater importance for their applications in various fields. This
present work also focuses the novel biological green material to synthesize the copper and cobalt oxide
nanoparticles. The copper oxide (CuO) and cobalt oxide (Co3O4) nanoparticles (nps)have been synthesized by
biological strategy utilizing AH (Araucaria heterophylla) gum extract. The characterization techniques, i.e. UV, GCMS,
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 confirm the formation of spherical
shaped (Co3O4) and oval shaped (CuO) isolated nanoparticles. The catalytic adequacy of the developed catalyst,
copper oxide (CuO) and cobalt oxide (Co3O4) nanoparticles was analyzed for the degradation of dyes: Methylene
Blue (MB), Congo Red (CR), Acid Violet (AV).The kinetic investigations for the reduction of synthetic dyes by the
nanoparticles were assessed and the reduction contemplates are very much fitted with the pseudo second order
kinetic model with less time.The antibacterial and antifungal activity of the prepared nanoparticles have been
evaluated against Escherichiacoli, Staphylococcus aureus, Bacillus subtilis, Aspergillusniger and Candida albicans.
