A magnetically recoverable scavenger for palladium based on thiol-modified magnetite nanoparticles Original Research Article

Modification of magnetite nanoparticles surfaces with thiol groups leads to a magnetically recoverable scavenger for metals. The magnetic solid removed Pd2+ ions from aqueous and non-aqueous solutions, and it was easily recovered with a magnet with no need of additional separation procedures. Scavenging efficiency of >99% was demonstrated. The magnetically recovered solid containing palladium-catalyzed the conversion of cyclohexene to cyclohexane for at least five successive reactions with TON ∼800 each. Magnetic separation capabilities greatly facilitate the recovery of the metal scavenger and catalyst.
