Paper Title:
Preparation of Ru Nano-Particles Dispersed on a Highly-Porous Material
  Abstract

Metallic ruthenium nano-particles supported on carbon were prepared from Ru3(CO)12 and highly-porous activated carbon by adsorption of the complex under boiling conditions in an acetone or cyclohexane solution, followed by H2 reduction at 200oC. Occupation of micropores with the precursor all through the carbon surface would diminish the BET surface area and the pore volume, whereas partial restoration of them by heating the material in H2 flow would be caused by complex decomposition and coagulative growth of Ru nano-particles (3.01 nm in average from TEM observation), which were surely lager in size than the pore diameter (2.15 nm determined by adsorption-isotherm measurements). Ru nano-particles were well dispersed on carbon.
