چکیده

Abstract In this study, Mn doped CdS/ZnO nanocomposites synthesized by co-precipitation method and its photocatalytic activity was tested using methylene blue under solar light irradiation. The prepared hybrid are characterized different physicochemical techniques including XRD, FESEM, EDX, TEM, UV-vis DRS PL analysis. From the XRD analysis, ZnO/CdS nanocomposite diffraction peaks only reflect binary crystalline structures of ZnO CdS. However, there is no characteristic peak found that may be because low content on ZnO/CdS. But (2.9 wt%) detected in nanocomposite, which measured EDX FESEM TEM results exhibit surface particle have spherical nature confirmed formation nanocomposites. degradation revealed admirable toward MB. reason for excellent indicates absorbance band shifted to red region reduction recombination photogenerated electron-hole, good agreement with UV-visible analysis study results. fitted kinetic plots showed a pseudo-first-order reaction model appropriate rate constants were 0.0068 min ?1 , 0.00846 0.0188 ZnO, 25 % CdS/ZnO, 0.8 mol% nanocomposites, respectively. maximum achieved 95% efficiency Hydroxyl superoxide radicals, having vital role MB, scavenging experiments. addition, recycling tests displays shown stability long durability. enhanced photodegradation potential treatment organic pollutants from textile wastewater.
