چکیده مقاله
This article represents the synthesis and characterizations of a Au NPs immobilized and carboxymethyl lignin CML modified Fe3O4 nanoparticles Fe3O4@CML/Au NPs following a bio inspired protocol without the participation of any toxic and harmful reducing or stabilizing agents The morphology and structural features were assessed following different physicochemical methodologies like Fourier Transformed Infrared Spectroscopy FT IR , Scanning Electron Microscopy FESEM , Transmission Electron Microscopy TEM , Energy Dispersive X ray Spectroscopy EDS , X ray Diffraction XRD , Vibrating Sample Magnetometer VSM and Inductively Coupled Plasma Optical Emission Spectroscopy ICP OES The Fe3O4@CML/Au NPs nanocomposite was successfully employed in the efficient reduction of different nitroarenes in aqueous medium An excellent yield were achieved within very short reaction time The nanocatalyst was easily magnetically recovered and recycled nine times without any significant loss of catalytic activity
