Abstract
|
A novel immobilized sparteine palladium (II) complex on the bio α-Fe2O3 nanoparticles was synthesized (Pd-Sparteine- α -Fe2O3). XPS, FT-IR, and ICP were used to determine compositional information. High thermostability and magnetic properties of it were proved by TGA and VSM, respectively. 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 2,4- dichlorophenol under visible light irradiation. It exhibited better photocatalytic efficiency of Pd-Sparteine-α-Fe2O3 was much higher than that of pure iron oxide nanoparticles. High yield and low reaction time of this catalyst were indicated that Pd-Sparteine-α -Fe2O3 could be a promising catalyst for direct photocatalyst applications.
