CuO Nanoparticles: Unveiling Photocatalytic Activity Through Comprehensive Review

– Their stability and endurance even when washed indicates that it cannot be easy to eliminate them, therefore, efforts should be made to develop new products with attributes that will ensure they arrest the formation of dyes. In the present study, we propose a simple and one-pot synthetic approach for the synthesis of CuO NPs; furthermore, to carry out the mechanochemical process, we use the bioactive extract of Seriphidium oliverianum leaves as a stabilizing and reducing agent. The identification of CuO NPs was confirmed through using Fourier-transform infrared spectroscopy (FTIR), photoluminescence (PL), scanning electron microscopy (SEM) and X-ray diffraction (XRD). A use of the UV-Vis spectroscopy technique enabled the monitoring of the photocatalytic activity of CuO NPs. CuO nanoparticles showed remarkable ability to disperse some of the commercial colours soluble in water. Per cent degradation for methyl green (MG) was 64% whereas that of methyl orange (MO) was 45%. 34% ~ 0. 313 and 64. 128% ~ 0. 468, respectively. When CuO NPs synthesized by the biomechanochemical process, it was revealed that CuO NPs proved very efficient in removing dyes from water.
