Nitroaromatics are toxic and generally delivered into the environment by the agrochemical and dye industries, so their removal through the reduction to corresponding amines is of particular importance from an environmental point of view. In the present work, amine - functionalized graphene oxide supported Rh (0) nanoparticles (Rh/GO - NH2) were prepared by the deposition- reduction method, and advanced techniques such as ICP - OES, P- XRD, XPS, TEM, HR- TEM and EDX have been applied to explain the structure and morphology of the catalyst. The results show that the Rh (0) nanoparticles are perfectly dispersed on the surface of the amine - functionalized graphene oxide. Then, the catalytic efficiency of Rh/GO - NH2 for the reduction of various substituted nitroaromatic compounds (Fig. 1) in aqueous solution at moderate conditions was investigated.
