Effect of exopolysaccharides on photocatalytic activity of ZnO nanoparticles

- ZnO NPs were synthesized by chemical co-precipitate method.
- The mean diameter was determined to be 55 nm.
- ZnO NPs exhibited excellent photocatalytic activity.
- Photocatalytic activity of ZnO NPs was evaluated based on the ability to degrade MB.
- Presence of EPS masks the photocatalytic activity of ZnO NPs.
