| 摘 要： | 以RuCl_3的乙二醇溶液作为产驱体，利用微波辐射技术合成了Ru/C(19.1 wt%) 纳米复合材料。TEM观察表明这些纳米粒子具有均匀的尺寸，其平均粒径为3.2 nm ，并均匀地分散在纳米碳的表面。Ru/C纳米复合在电化学氧化后可以作为电化学超 级电容器的电极材料，循环伏安实验表明其比电容为144 F/g，而未负载纳米钌的 XC-72碳的比电容为31 F/g。 |

| Abstract: | Ru/C nanocomposite was prepared by microwave heating. TEM imaging shows a high dispersion of Ru particles with a mean diameter of 3 2 nm and uniform size on the carbon support. After electrochemical oxidation of the Ru nanoparticles to ruthenium oxide nanoparticles, the resulting RuO x /C nanocomposite could be used as an electrochemical supercapacitor material to increase the specific capacitance of carbon (XC-72) from 31 F/g to 144 F/g. |
| Keywords: | microwave Ru/C nanocomposite electrochemical supercapacitor |
