Abstract

In this work, we reported a facile and environmentally friendly approach for the preparing of 3D graphene/Pt aerogel by gamma irradiation at room temperature. Graphene oxide (GO) and platinum ion are simultaneously reduced and self-assembled into a three-dimensional (3D) macro porous structure. Pt NPs with diameter between 2.3 and 5.5 nm were homogeneously attached onto the graphene sheets of the 3D network structure. The catalytic efficiency towards the degradation of methyl orange (MO) of the 3D GA/Pt composite is 108 times higher than that of the pure Pt NPs under the same experimental conditions.
