A simple and facile method is described for the in situ synthesis of graphene oxide-Ag nanoplates (GO-AgNPs) hybrid structure and then served as sacrificial templates for producing graphene oxide-Au nanorings (GO-AuNRs) by galvanic replacement taken place on the GO surface. The catalytic activity of the resulting hybrid nanomaterial has been investigated for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride (NaBH4). The results showed that the rate constant of GO-AuNRs nanomaterials was 0.205[Formula: see text]min[Formula: see text] and the samples showed significant enhancement in catalytic activity.

Ag nanoparticles are in situ decorated on a BNNS modified with a TA–Fe complex, and the nanohybrids show excellent catalytic activity.
