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/RuO2·xH2O的超级电容性质明显提高(10 mV/s 时229 F/g ).
Carbon/nano Ru composites were obtained by silica templating of dichlorobis(μ-chloro)bis[(1-3-η: 6-8-η)-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.
