One-pot synthesis of stabilizer-free Ag-Graphene Nanocomposite and its potential application on photodegradation of RhB

Abstract

Simultaneous reduction of graphene oxide (GO) and silver nitrate (AgNO3) into stabilizer-free Ag-Graphene Naoncomposite (AGN) using DMAc-assisted thermal reduction method with controllable density of Ag nanoparticles (Ag NPs) is reported. Microscopy techniques (scanning electron microscopy and high-resolution transmission electron microscopy) have been employed to probe the morphological characteristics of AGN and the lattice plane of Ag NPs. We observed a significant improvement on adsorption ability of AGN-P25 mixture compared with bare P25, indicating potential application on photocatalysis of AGN.
