Abstract

The best of both worlds: The synthesis of carbon-encapsulated iron-based magnetic nanoparticles is described (see picture: left TEM image, right model). With such small catalysts that have macroscopic magnetic properties, the advantages of homogeneous or colloidal and heterogeneous catalysts can be combined.
