Influence of CdO-doping on the photoluminescence properties of ZnO nanofibers: Effective visible light photocatalyst for waste water treatment

► Novel CdO/ZnO nanofibers are introduced as photocatalysts under sun lights. ► Scientifically, the study affirms that low CdO content is more preferable. ► The proposed nanofibers were manufactured using simple and effective technique. ► Theoretical explanation of the degradation mechanism is introduced.
