Synthesis of Cd-substituted NiCoPrFe2O4@CNTs via sol-gel method: Investigating the structural and photocatalytic properties

Abstract

The present study investigates the photocatalytic activity of NiCoPrFe2O4 and Cd-NiCoPrFe2O4 synthesized by the self-ignition sol-gel process. NiCoPrFe2O4@CNTs was prepared via ultrasonication approach. Methyl violet was used as a dye to examine the photodegradation activities of synthesized photocatalysts under visible light. The spinel crystalline structure is confirmed by XRD. The morphology of the as prepared samples was observed via scanning electron microscopy. NiCoPrFe2O4, Cd-NiCoPrFe2O4, and NiCoPrFe2O4@CNTs showed 55.46%, 78.29%, and 85.96% percentage degradation of methyl violet respectively. The photocatalytic performance of CNT based nanocomposite is found to be increased due to the enhanced charge separation property of CNT. © 2023 Elsevier B.V.
