Copper oxide nanoparticles(Cu O Nps) were successfully synthesized by solution combustion method using aqueous leaf extract of Rauvolfia serpentina as a fuel. The structure and morphology of the Cu O nanoparticles(Nps) were characterized by powder X-ray diffraction(PXRD), UV–visible spectroscopy(UV–visible), scanning electron microscopy(SEM), transmission electron microscopy(TEM), etc. The PXRD patterns reveal the formation of monoclinic phase with crystallite structure. SEM images indicate that the particles have sponge-like structure being highly porous and agglomerated with large surface area. The average crystallite sizes were found to be in the range of 10–20 nm by Scherrer’s method. The Cu O Nps size was further confirmed by TEM. Further, Cu O Nps exhibit good photocatalytic activity for the photodegradation of trypan blue dye, indicating that it acts as a promising semiconducting material. The antibacterial properties of Cu O nanoparticles were investigated against pathogenic bacterial strains, namely Gram-ve Escherichia coli(NCIM-5051) and Pseudomonas desmolyticum(NCIM-2028) and Gram ?ve bacteria Staphylococcus aureus(NCIM-5022) using the agar well diffusion method.
