چکیده انگلیسی
In this work, magnetically separable Fe3O4 nanoparticles were synthesized in the presence of natural κ-carrageenan (KCAR) biopolymer to provide Fe3O4@KCAR. FT-IR analysis, scanning electron microscopy (SEM), X-ray diffraction, VSM analysis, and SEM-EDAX were incorporated for the characterization of Fe3O4@KCAR nanocomposite. And then, the first catalytic report of Fe3O4@KCAR with no post-modification was achieved by studying its catalytic activity in the multicomponent reaction of rhodanine synthesis. Based on this study, Fe3O4@KCAR was an efficient, magnetically separable and recyclable, water-dispersible and green catalyst with natural source. This catalyst also showed 9-run recyclability with no significant yield decrease.
