Modifications of graphenes have been studied to develop a multi-functional supporting platform for catalytic applications due to their advantages like high surface area, conductivity and thermal stability. In this research, individual graphene oxide(GO) sheets were exfoliated from graphite via consecutive acid and peroxide treatments. Pd nano-particles were deposited on the GO surface using Pd2+ ion exchange where the epoxide, hydroxyl, ketone and carboxyl groups on the graphene oxide sheets act as nucleation sites of Pd nanoparticles and their dispersions. The thermal treatments of the Pd-GO in H2 flow produced Pd-Graphene complexes and their catalytic performances in Suzuki & Sonogashira reaction were investigated using microwave reactor. Morphological and chemical structures of the GO, Pd-GO, and Pd-Graphene were investigated using FT-IR, XRD, TEM, and EDX. Finally, their catalytic performances in Sonogashira reaction have been investigated.
