• Resumen

  • Carbon nanotubes (CNT) and graphene are recently discovered carbon nanomaterials which find application in a great number of fields. Their excellent mechanical, electrical, thermal and chemical properties make them useful for a wide range of new developments which move from electronic devices to drug-delivery systems. In addition, catalytic systems usually employ carbon nanotubes and graphene in any of the stages of the catalytic process. In this work, the integration of carbon nanotubes and graphenic materials in well-known homogeneous catalytic systems, i.e. unsaturated-substrates reduction reactions by means of hydrogen transfer processes catalyzed with iridium N-heterocyclic carbene complexes is studied. The employment of different strategies for the preparation of the supports, the design of the nanostructure functionalization routes with the metallic complexes and the study of the catalytic activity of the final hybrid materials are described. Both types of materials were oxidized with the aim of developing oxygen functional groups which allow nanomaterial functionalization methods to be applied with the organometallic compounds. A special effort was made to accomplish a complete and exhaustive characterization of the involved samples by typical solid characterization techniques.
