ABSTRACT

Lately, due to excessive usage of chemicals and dyes, the quality of water in the reservoir has degraded. For the treatment of water, primary secondary, and tertiary treatment was used but the drawback for the same was secondary pollution. Recently, advanced oxidation processes and photocatalysis were used for the treatment of water, whereupon excitation by light, catalyst creates holes and electrons which help for degradation dye. In this work, Zinc oxide photocatalyst was synthesized with chemical technique and green technique. Synthesized photocatalyst was characterized by FTIR. Later these photocatalyst was tested against dye degradation of methylene blue and their performance was compared. The result showed better performance for chemically synthesized photocatalysts. Keywords: Dye degradation, photocatalysis, green synthesis, ZnO photocatalyst
