▎ 摘　　要

The present work reports about one-pot hydrothermal synthesis of a composite of Ag/Fe2O3 anchored on reduced graphene oxide (rGO) via homogeneous chemical precipitation of Fe(OH)(3) and simultaneous reduction of Ag(I). The pristine aqueous suspension of graphene oxide (GO) synthesized by Hummers method is mixed with Fe(NO3)(3)center dot 9H(2)O, AgNO3, urea and polyethylene glycol (PEG 4000). The mixture under hydrothermal conditions transforms into Ag/alpha-Fe2O3-rGO nanohybrid. Here PEG 4000plays dual role of surfactant as well as reducing agent for Ag(I). The synthesized Ag/Fe2O3-rGO nanocomposite was used as magnetically recoverable catalyst for room-temperature chemoselective reduction of aromatic nitro groups to the corresponding amines.
