Ag/AgBr/rGO nanocomposite: Synthesis and its application in photocatalysis

• Ag/AgBr/rGO composite was synthesized via a facile solution-mixing method.
• The hybrid process can prevent the aggregation of Ag/AgBr and rGO.
• Ag/AgBr/rGO showed enhanced photocatalytic performance.

Ag/AgBr is a highly efficient visible-light plasmonic photocatalyst but suffers from severe aggregation of the particles. To settle this problem, we simply added a small amounts of graphene oxide (GO) to the Ag/AgBr reaction system. Expectedly, well monodispersed Ag/AgBr particles bonded on the rGO sheets (Ag/AgBr/rGO) was obtained, as observed by SEM. The adsorptive and photocatalytic activities of the as-prepared samples were investigated by degradation of RhB under visible light irradiation. Compared with pure Ag/AgBr, Ag/AgBr/rGO nanocomposite shows enhanced performance in both the adsorptive and photocatalytic activities.
