Photocatalytic Degradation of Ortho‐Nitrophenol using ZnO‐β‐CD Nanocomposite

Abstract

AbstractPhenolic compounds are present as pollutant in the industrial waste water. The present work deals with the photocatalytic degradation of Ortho‐Nitrophenol by using Zinc oxide Nanoparticles (ZnO NPs) and its composite with β‐Cyclodextrin (β‐CD) represented as ZnO‐β‐CD. ZnO NPs were prepared by using Sol Gel Method. The morphological and structural properties were studied using SEM EDAX, PXRD, FT‐IR and UV‐DRS. Effect of pH was also studied. ZnO NPs degraded the Ortho‐Nitrophenol up to 25.8 % and it was enhanced by the addition of β‐CD up to 88.9 % in 100 minutes. Catalysts used were 1 g/L during the degradation.
