Abstract

Gold and ruthenium nanoparticles have been self-assembled on graphene oxide by using cysteine or glutamic acid junctions as heterogeneous nanocatalysts in the reduction of nitroaromatics. It was observed that the reaction rate of Au/Ru nanoparticles decorated on graphene oxide sheets via additional glutamic acid junctions was higher than catalyst decorated via cysteine junctions.
