A Facile Synthesis of GO/CuO Nanocomposite with Enhancing Photocatalytic Activity for the Degradation of Azure-B Dye and Its Antimicrobial Behavior

Green method for synthesis and characterization of copper oxide nanoparticles using Mulberry plant extract and their antibacterial, antioxidant and photocatalytic activity

“…The pure CuO nanoparticles under sunlight irradiation exhibit better degradation due to their e-h pair restriction [42]. The UV light irradiation induces the OH radicals which can dissociate the dye compounds into noxious products [43][44][45][46]. The lowest bandgap and combination of other materials enhanced the catalytic activity because of their large surface area and electron tapping on the surface [45][46][47].…”

Experimental and computational study of metal oxide nanoparticles for the photocatalytic degradation of organic pollutants: a review

“…Among these, the CuO composite with carbon-based materials has attracted great attention. Banu et al 192 synthesized GO/CuO nanocomposite by the hydrothermal method for the photocatalytic degradation of azure-B dye with an efficiency of 95%. The enhanced photocatalytic activity of the prepared nanocomposite was attributed to the small size and high surface area of GO/CuO.…”

Synthesis and process parametric effects on the photocatalyst efficiency of CuO nanostructures for decontamination of toxic heavy metal ions

“…Banu et al [55] investigated the influence of varying solution pH from 5 to 9 on the photocatalytic degradation proficiency of CuO/GO catalyst to brilliant green dye with other variables fixed and found an increasing tendency of degradation with pH till the optimal value at 7.5 and decreased afterward. They attributed this decreasing tendency at higher pH values to the poor adsorption of dye molecules on catalyst surface owing to a decrease in Coulombic attraction between cationic dye molecules and anionic catalyst surface in the presence of excess HO − ions at such high pH values.…”
