摘要: Herein, we describe a green and eco-friendly synthesis method for preparing Cu/RGO/Fe3O4 nanocomposite through biological reduction of graphene oxide Cu2+, Fe3+ ions using Euphorbia wallichii leaf extract as reducing stabilizing agent. UV-vis spectroscopy FT-IR analysis were used characterization the resulting nanoparticles. The synthesized was characterized by FESEM, EDS, TEM, FT-IR, XRD, BET, VSM elemental mapping then successfully magnetically separable reusable catalyst 4-nitrophenol (4-NP) Rhodamine B (RhB) in water at room temperature. Interestingly, heterogeneous recyclable magnetic can be easily separated bar recycled several times without any significant loss catalytic activity.
