摘要报道了一种利用氧化硅模板,裂解简单易得的含钌有机物制备纳米结构炭/钌复合物的方法。在该复合物中,钌纳米颗粒均匀地分布在多孔的炭基体中。该复合物被电氧化所得炭/RuO.2xH2O的超级电容性质明显提高(10mV/s时229F/g )。 Carbon/nano Ru composites were obtained by silica templating of dichlorobis （μ-chloro）bis [ （ 1-3-η： 6-8- η-0） -2,7-dimethyloctadienediyl ] diruthenium （ IV ）, followed by pyrolysis. Carbon/RuO2 ·xH2O 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· xH2O composites displayed improved capacitive properties （229 F/g at 10 mV/s ） as electrodes of supercapacitors in H2SO4 electrolyte.
