▎ 摘  要

AuCu and AgCu bimetallic nanoparticles supported on guanidine-grafted reduced graphene oxide nanosheets (AuCu@G-rGO and AgCu@G-rGO) were synthesized and characterized by FAAS, X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) analysis. The synthesized catalysts have been investigated in the reduction of nitroarenes and the tandem synthesis of tetrahydro-1H-benzo[b][1,4] diazepine-2-carboxamide and 1H-tetrazolyl-benzo[b][1,4] diazepine derivatives.
