Abstract:
Dyes present in industrial wastewater are harmful to humans as well as environment. They are non biodegradable synthetic materials that are difficult to degrade naturally. At present the simplest, economical
and ecofriendly method for dye degradation is application of metal oxides nanocomposite as photocatalyst.
Fabrication of metal oxide nanocomposites by using safe and cheap natural products for photocatalytic
degradation of dyes is highly interesting field in material sciences. This research focuses on synthesis of four
different kinds of nanocomposite CoO/Agcl/FeO, CoO/Agcl/NiO, CoO/Agcl/CuO, CoO/Agcl/ZnO which
further processed with sodium alginate and form nanocomposite beads. The synthesized nanocomposites
beads were characterized by FTIR. Futhure more, synthesized nanocomposite beads were employed as
photocatalyst for the degradation of model dye methyl orange . The degradation of model dye was recorded
high for Iron/alginate nanocomposite beads(90% in 80 mins) as compared to other nanocomposite beads.
