Graphene oxide (GO) serves as a precursor to various technologies, which include batteries, biosensors, solar cells, and supercapacitors. Metal hybrids of GOx enhance the sensitivity and electrical conductivity for sensing and catalytic applications. In this project we use silver and palladium nanoparticles independently to modify the surface of GOx. Silver nanoparticles exhibit optical properties that play a role in bacterial resistance, demonstrating its role in various biomedical sensors. Palladium nanoparticles are highly sensitive and functional in room temperature; making it an ideal metal for catalytic applications. Here we report the synthesis of functional graphene oxide from graphite flakes, followed by both successful carboxylation and reduction. In this experiment, carboxylation of GOx was followed by insertion of silver nanoparticles through an oleylamine ligand. Reduction of GOx resulted in a highly conductive, monolayer graphene quantum dot, which will be coated with palladium nanoparticles and utilized in catalytic applications, primarily Suzuki cross-coupling reactions. The Pd-GOx will serve as a cheaper and stable alternative as compared to traditional palladium-based catalysts used in these reactions. Initial results of our experiment will be presented.<br/>
