In this study, Ag3PO4 decorated nitrogen-doped graphene (Ag3PO4@NGR) nanocomposite has been synthesized via a simple ultrasonic method. The as-synthesized Ag3PO4@NGR shows significantly enhanced photocatalytic performance towards eosin yellow to non-toxic simple molecules. 99% degradation of EY is able to be achieved in 50 min. The photocatalytic reduction conditions (ultrasound power, frequency and time) were optimized and discussed. The highly enhanced activity of the Ag3PO4@NGR nanocomposite was attributed to the fast electron-accepting and -migrating properties of NGR. Lastly, the enhanced photocatalytic mechanism associated with the Ag3PO4@NGR nanocomposites was studied and investigated. The results of this research work testified that Ag3PO4@NGR could be used as an ideal candidate for the environmental treatment and beyond.
