CdS Coated Mn Doped ZnO Nanospheres as Textile Catalyst: Fabrication, Physicochemical Techniques and Dye Removal Under Natural Light

ZnO as a promising photocatalyst has gained much attention for the removal of organic pollutants from water. However, main drawbacks relatively low photocatalytic activity and high recombination rate photo excited electronhole pairs, restrict its potential applications. Promoting spatial separation charge carriers is paramount signi? cance photocatalysis, because dierence in band positions make gradient at composite boundary. In this work, our aim to enhance efficiency CdS coated Mn doped nanospheres under solar light irradiation. Objectives work are, fabricate by simple ethanolic dispersion method, applied testing methylene blue (MB) dye. The fabricated binary composites were analyzed with different physicochemical techniques like PXRD, SEM EDX, UV-DRS, PL TEM. degradation results have revealed that, exhibits admirable toward MB. remarkably enhanced can be interpreted terms lots active sites, which efficiently separate generated electron holes. A plausible mechanism also elucidated via species trapping experiments various scavengers, indicating that O2 -and. OH radicals play crucial role reactions visible This suggests rational design construction heterostructures powerful developing highly efficient, reusable visible-light photocatalysts environmental purification energy conversion. indicates nanocomposite treatment textile wastewater.
