A novel heterogeneous Pd catalyst was synthesized by anchoring palladium (II) onto poly (undecylenic acid-co-N-isopropylacrylamide-co-potassium 4-acryloxyoylpyridine-2, 6- dicarboxylate)-coated Fe3O4 (Fe3O4@ PUNP) magnetic microgel. The catalyst (Fe3O4@ PUNP-Pd) was characterized by FT-IR, TEM, VSM, XRD and XPS, and the loading level of Pd in Fe3O4@ PUNP-Pd catalyst was measured to be 0.330 mmol g− 1 by AAS. This ...
