Dumbbell-like Au-Fe3O4nanoparticles and their single-component counterparts, Au and Fe3O4, were compared regarding their H2O2 reduction capability. The Au-Fe3O4 nanoparticles are catalytically more active, which is attributed to polarization effects from Au to Fe3O4. This activity can be further tuned by the size of the nanoparticles.
