The management of waste material for the environmental remediation is the fast growing field of research. Dyes and organic molecules are extensively used in the textile industry and unused content is discharged into the nearby water resources. This creates severe problems in the aquatic system. In this direction, our recently synthesized photocatalyst CeO₂/Zeo-NaX derived from coal fly ash is employed for the visible light degradation of cationic charged dye methylene blue, anionic charged dye methyl orange and neutral organic compound p-nitroaniline. The study reveals that the photocatalyst is more efficient towards the degradation of cationic dye (methylene blue) over anionic dye (methyl orange) and neutral organic molecule (p-nitroaniline).
