Core–Shell Fe–Pt Nanoparticles in Ionic Liquids: Magnetic and Catalytic Properties

The reaction of Fe(CO) 5 and Pt 2 (dba) 3 in 1- n -butyl-methylimidazolium tetrafluoroborate (BMIm.BF 4 ), hexafluorophosphate (BMIm.PF 6 ), and bis(trifluoromethanesulfonyl)imide (BMIm.NTf 2 ) under hydrogen affords stable magnetic colloidal core–shell nanoparticles (NPs). The thickness of the P…
