The introduction of plastic waste into water bodies may lead to many adverse environmental impacts as the plastic debris is very stable and generally requires a longer time to degrade. Heterogeneous photocatalysis using zinc oxide (ZnO) semiconductor has recently emerged as an effective way to degrade organic pollutants including dyes.

The optimal amount of Ag deposition was found to be 0.1 mol/l.
