Synthesis of Spherical Copper Oxide Nanoparticles by Chemical Precipitation Method and Investigation of Their Photocatalytic and Antibacterial Activities

Methylene blue (MB) dye and Staphylococcus aureus (S. aureus) bacteria in wastewater are the two significant problems currently. Researchers have been looking for materials that can combat these at same time. In present study, we describe synthesis of spherical copper oxide (CuO) nanoparticles (NPs) by chemical precipitation method evaluate their photocatalytic performance against MB antibacterial efficacy S. aureus. CuO NPs were produced using acetate monohydrate (Cu(CH3COO)2·H2O) as precursor sodium hydroxide (NaOH) reducing agent. Synthesized characterized a combination techniques, including ultraviolet–visible spectroscopy, X-ray diffraction, transmission electron microscopy, selected area Fourier transform infrared, energy-dispersive diffraction analysis. All analyses indicated monoclinic formed with shape an average particle size 6.2 nm. Photocatalytic experiments 55.5% 10 ppm solution was degraded prepared nano-CuO photocatalyst only after 60 min. Additionally, synthesized demonstrated, to some extent, zone inhibition on bacterium’s cell wall. It is inspiring be used solve contamination bacterial infection simultaneously.
