Abstract: Solution-processed graphene oxide is most useful because it can be used to prepare graphene-inorganic and graphene-organic compounds. The high surface area and electrical conductivity of graphene provide the motivation for studying its processing and energy-related applications. Reduced graphene oxide (rGO) offers large lithium storage capacity but the presence of surface traps limits its Coulombic efficiencies, thus the mechanism of Li intercalation is studied using various spectroscopic techniques. A new synthetic method to produce organic-graphene hybrids was developed. Due to the strong non-covalent interactions with organic molecules, rGO was used as a template for the growth of 1D organic nanostructures, producing unique core-shell hybrid which shows improved photovoltaic properties. We also examine the use of rGO as a platform for the dispersion and immobilization of metal nanoparticles. Excellent charge transport property of rGO renders it an effective electron mediator fuel cell and photocatalytic applications (eg. CO2 fixation and water splitting).
