Compared with bare Bi spheres, the Bi/GO nanohybrids exhibited highly enhanced Received in revised form 8 May 2017 and stable direct plasmonic photocatalytic activity towards removal of NO, primarily resulting from the Accepted 12 May 2017 assistance of graphene oxide. The Bi spheres act as antenna for incident light absorption via the SPR effect. Available online 15 May 2017 The graphene oxide is regarded as an acceptor and transporter of the photogenerated electrons and pro- vides the binding sites for Bi deposition. Furthermore, the rel
