Magnetic nanoparticle supported polyoxometalates (POMs) via non-covalent interaction: reusable acid catalysts and catalyst supports for chiral amines.

Magnetic polyoxometalates (POMs) are obtained by a simple sonication between functionalized magnetic nanoparticles and polyoxometalates. This material can be used not only as a highly active acid catalyst, but also as a catalyst support for chiral amines.
