Carbon/nano Ru composites were obtained by silica templating of dichlorobis (mu-chloro) his [(1-3-eta: 6-8-eta) -2,7-dimethyloctadienediyl] diruthenium (IV), followed by pyrolysis. Carbon/RuO2 center dot xH(2)O composites were obtained by electro-oxidation of carbon/nano Ru composites. It was found that the carbon/Ru composites had homogeneously dispersed Ru nanoparticles in the hierarchical pore structures and carbon matrix. The carbon/RuO2 center dot xH(2)O composites displayed improved capacitive properties (229 F/g at 10 mV/s) as electrodes of supercapacitors in H2SO4 electrolyte.
