Biomolecules and microwaves directed fabrication of Ag/CeO 2 nanocomposite: a versatile candidate for the degradation of textile dye mixtures and antibacterial studies

In this work, Ag/CeO 2 nanocomposite was prepared by facile process. Microwave assistance was utilized in accordance with green synthesis to tailor the morphology of the synthesized nanocomposite. Oryza sativa L. indica rice extract is elected as bio reductant for the formation of CeO 2 nanorods and CeO 2 /Ag nanocomposite. The adopted synthesis yielded 1D nanorods like structure for CeO 2 as well as spherical shaped Ag nanoparticles surmounted the CeO 2 nanorods with nanocomposite fabrication. The existence of AgNPs within CeO 2 nanorods was confirmed with analytical techniques. The fabricated Ag/CeO 2 nanocomposite was applied for its utilization in dyes degradation for water treatment. Individual dye solutions of MB, MO were treated with the Ag/CeO 2 nanocomposite eases higher degradation efficiency of 94.84% within 7 min, 88% within 5 min, respectively. The fabricated nanocomposite is well suited for real time dye water treatment discharge from industries, for the reason that its efficacy in degradation with dye mixtures (MO + RhB) was evaluated within 12 min. Bactericidal properties were also elucidated with human pathogens of B. subtilis, V.cholerae exhibited superficial inhibition values of 25 mm as well 17 mm for the elected microorganisms, again proves the fabricated nanocomposite as potential candidate for environmental applications.
