Synthesis and Characterization of a Novel Bio-Magnetically Recoverable Palladium Nanocomposite for the Photocatalytic Applications

A novel immobilized sparteine palladium (II) complex on the bio α-Fe۲O۳ nanoparticles was synthesized (Pd-Sparteine- α -Fe۲O۳). XPS, FT-IR, and ICP were used to determine compositional information. TGA and VSM, respectively proved high thermostability and magnetic properties of it. The size and morphology of this heterogeneous catalyst were investigated using SEM and TEM. Photoluminescence spectrum, BET, DRS, and EDAX of this novel nanocomposite were evaluated for further investigations. The synthesized magnetic nanohybrid was successfully exploited as a new recyclable heterogeneous photocatalyst in the degradation of ۲,۴- dichlorophenol under visible light irradiation. It exhibited better photocatalytic efficiency of Pd-Sparteine-α-Fe۲O۳ than that of pure iron oxide nanoparticles. This catalyst's high yield and the low reaction time indicated that Pd-Sparteine-α -Fe۲O۳ could be a promising catalyst for direct photocatalyst applications.
