Synthesis and characterization of platinum-decorated iron carbide nanoparticles and their potential for magnetically induced catalysis

Abstract

A mild organometallic synthetic approach to platinum-decorated iron carbide nanoparticles (Pt@ICNPs) is reported. The resulting ferromagnetic Pt@ICNPs can be activated upon exposure to alternating current magnetic fields (ACMFs, magnetic induction), with a specific absorption rate of 625 W g⁻¹ at 47 mT, 100 kHz. Pt@ICNPs are a versatile multifunctional platform with significant potential for applications in biomedicine and magnetically induced catalysis. The latter is demonstrated herein via the magnetically induced hydrogenation of various functionalities under mild conditions.
