In the last fifteen-years, the application of metal nanoparticles as catalysts in organic synthesis has received a
renewed interest. Therefore, much attention is currently being paid to the synthesis of metal nanoparticles in order to
achieve the control of their characteristics in terms of size, shape and surface chemistry. Besides this, the recyclability as
well as the recovery from the reaction medium still remain the major drawbacks to widespread the use of nanoparticles in
catalysis. To overcome these problems, the immobilization of metal nanoparticles on solid supports appears as a promising
alternative. In that context, carbon materials offer several advantages as solid supports such as availability, relatively
low cost, high mechanical strength, chemical stability, and a pore structure along with an attractive surface chemistry
which allows easy modifications, such as its functionalization, to suit the nanoparticles immobilization needs. Among the
transition metals Palladium and Ruthenium are widely employed as efficient catalysts in many reactions. Herein, the most
recent advances, from recent papers and patents, in relation to the preparation of carbon-supported Pd or Ru nanoparticles
systems as well as their application as catalysts in alcohol oxidation, cross-coupling or hydrogenation reactions, are reviewed.
