Abstract

Because of the related benefits, green techniques of synthesizing cobalt oxide nanoparticles (Co₃O₄-NPs) have been preferred these days over different methods. The Co₃O₄-NPs in this study have been produced utilizing the waste peels of Ananas comosus (pineapple) and cobalt (II) chloride as a source of cobalt. Several methods, including Fourier transform spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), UV- spectrophotometer were used to analyze the produced NPs. The produced Co₃O₄-NPs’ antibacterial properties have been determined against gram positive bacteria and found active against Bacillus subtilis (B.subtilis) via Diffusion from Agar Well Method. This recently created green synthesis technique is not harmful to the environment and may replace physical and chemical processes of Co NPs.
