The Pd NPs@Fe3O4-lignin was characterized by TEM, XRD, EDS, FE-SEM, FT-IR, VSM, and UV–Vis. The magnetic NPs were employed as exceptional catalysts in the catalytic reduction of Cr(VI) and Suzuki-Miyaura reaction between PhB(OH)2 and substituted aryl halides in EtOH:H2O as well as under ligand free conditions in the presence of K2CO3 with satisfactory product yields. Regeneration of the Pd NPs@Fe3O4-lignin was carried out by a magnet after the preparation of biphenyls. Catalytic efficiency retention was achieved after seven cycles.eninfo:eu-repo/semantics/embargoedAccessBiowasteCr(VI) ReductionHibiscusRosasinensis L.Pd NPs@Fe3O4-ligninSuzuki-MiyauraArticle148---31935407Q1WOS:000522094600027Q1
