Abstract:The present work demonstrates a simple and sustainable method for forming azo oligomers from low-value compounds such as nitroaniline. The reductive oligomerization of 4nitroaniline was achieved via azo bonding using nanometric Fe 3 O 4 spheres doped with metallic nanoparticles (Cu NPs, Ag NPs, and Au NPs), which were characterized by different analytical methods. The magnetic saturation (M s ) of the samples showed that they are magnetically recoverable from aqueous environments. The effective reduction of ni… Show more
