ABSTRACT
In this article, we report a simple method to fabricate graphene and Ag nanoparticles (NPs) composite aerogel (GA/Ag). The GO and Ag ions were in situ reduced by gamma-ray irradiation and went through self-assembly three-dimensional (3D) honeycomb-like porous composite aerogel in the presence of isopropanol. Measurements using XRD, XPS, SEM, TEM revealed that the GO and Ag ions can efficiently reduction into rGO and Ag NPs. In addition, Ag NPs were homogeneously attached to the graphene nanosheets of the honeycomb-like porous structure and had a typical diameter of 30–70 nm. Thus the gamma-ray irradiation-induced synthesis is an efficient method for preparing 3D GA/Ag composite.
