Graphene has attracted great interest for a fundamental understanding of its unique structural and electronic properties and also for applications in heterogeneous catalysis where nanoparticle catalysts can be efficiently dispersed on the graphene nanosheets. In this talk, the application of graphene as a catalyst support for the Fischer-Tropsch Synthesis (FTS) of liquid fuels will be presented. We describe the synthesis of a new class of FT catalysts supported on graphene and report on their high activity and selectivity for the production of long-chain hydrocarbons. The simultaneous chemical reduction of the metal precursors and graphene oxide in water under microwave irradiation allows the deposition of well-dispersed metal nanoparticles on the defect sites of the graphene nanosheets. The Fe-K-graphene catalyst exhibits high activity and selectivity towards C8+ and higher products with excellent stability and recyclability. The exceptional activity and stability of the FTS-graphene catalysts will be presented and discussed.
