چکیده
ABSTRACT. In this work, synthesized carbon quantum dots (CQDs) and zinc oxide nanoparticles (ZnO NPs) are used to form ZnO/CQDs nanocomposite. The characterization of nanocomposite using X-ray diffraction (XRD) indicates that ZnO NPs have the same profile, suggesting presence CQDs does not impinge crystal structure in Besides, an analysis performed with scanning electron microscopy (SEM) displays plate-like nanostructure average thickness about 22 nm 25 for ZnO/CQDs, respectively. Furthermore, reflectance study visible range shows a reduction sunlight reflection intensity compared NPs. addition, photocatalytic studies indicate rate degradation methylene blue (MB) nanocomposites is higher than Indeed, optimized conditions, activity can reach 100% within 45 min exposure 7.5 mg/L MB while it takes 90 under conditions. These fascinating results attributed reflective properties ZnO/CQDs.
