Graphene Supported PtNi Nanoparticles as Magnetically Separable Nanocatalysts

Abstract EN

Efficient recovery of nanocatalysts, especially the graphene supported noble metal catalysts, is a challenge.

In this study, we report a simple one-step route to prepare the graphene supported Pt/Ni nanocatalysts with ideal superparamagnetic properties.

We demonstrated that they had excellent catalytic activities in the catalytic reduction of aromatic nitro compounds and could be easily separated from the reaction mixtures by applying an external magnetic field.
